@Goji that's a simplification; I believe the reason they were saying the swimming thing was debunked was because of the center of mass. Basically, where it would sit on the body would make Spino extremely unstable and cause it to have to constantly fight flipping over onto its side, like a toy in a bathtub. This could also be an issue with the Chimera situation though, or some missing information, like swallowed rocks or an air bladder.

I think it would be funny if in a few years after this whole time debating the anatomical nature of Spinosaurus, a perfect complete specimen is finally discovered and it turns out it always walked on two legs.
Imagine if we find out that there are multiple species of Spino. One behaves like the Jp3 version (land based carnivore with shorter, sturdier snout and longer legs), one is basically the giant heron (semi-aquatic, medium sized legs, long snout, padded tail) and the other is practically a crocodile (very short sail, long snout, long paddle like tail)
@@quakethedoombringer tbh, I've always thought about this a lot when it comes to debating about Spinosaurus anatomy. It wouldn't be too farfetched either, we already have other Spinosaurids such as Suchomimus, Baryonyx, and Irritator so to have another species of Spinosaurus that it's bit more closely related to the actual Spinosaurus would be very exciting. Like Tarbosaurus to Tyrannosurus.
@Holy Crusader I haven't seen it yet personally but I have read through the latest paper published on it. It in fact walked on 2 legs. Edit: nvm more recent papers came out. F this genus.
I mean...we literally discus about sizes of dunkleostetus and all we have about that thing is a friggin skull bone lmao I feel like people are playing "we don't have much specimen" card in this case just because their favourite "hyper predator" is slowly becoming land whale at this rate lmao.
We're going to keep having these back and forth, he said she said, debates until we can find a reasonably complete specimen that we are sure is ACTUALLY Spinosaurus instead of a hodgepodge of different specimens that may or may not be the same species or genus slapped together and roughly scaled to each other. It's becoming increasingly frustrating when you have a new paper coming out every week that is more or less going back and forth between the same arguments when we aren't even sure the reconstruction we have is particularly accurate. Things like this are what drives the public away from the science of these animals, when we should be doing everything in our power to draw them in.
If only that submarine wasnt destroyed long agooo, hope we find a full specimen, cause boy they do go back and forth with the Quad/Bipedal argument (unless proved otherwise,i always thought it was bipedal cause of the structure of its claws).
The strangest part about the legs is that all of it's relatives have proportional legs. The tail just adds on top of the confusion to how such a thing could get around bipedially
see? its that reason that I'm convinced we found juvenile back legs, this whole thing just seems completely off, and the further down the Spino trail we have gone, the sadder this poor creature has become.
@@TS-7864 similar age does not immediately correlate with similar size, is there no chance the specimen that the legs came from was malnourished or stunted in some way? think of the variance in every day animals, let alone humans, even if they're close in age
I was suspecting back then due to how different Spino looked compared to its supposed relatives, i thought it probably isn't in the same family as them. Imagine if Spino and Oxalaia get taken out from Spinosaurid family and the family gets renamed to Suchomimid
I believe that Spinosaurus' sail was a Solar Panel used to power up it's propeller tail which it used both to travel in water like a boat and to fly in the air like the rotor of an helicopter
Everyone's favourite huge crocoduck platypus of the theropods has had been in so many changes, and it will keep going on as long as new wack stuff gets to be discussed everytime.
I’ve been making this kind of statement ever since 2014, and it’s nice to see some biomechanical research done on this. I literally never understood how an animal of this size could support it’s own mass with hind limbs that are smaller than it’s own arms.
It also doesn't make sense for Spinosaurus to be quadrapedal either since its front limbs were not adapted to that kind of lifestyle. So, in the end, we just don't know. We can only wait until more Spinosaurus fossils are found.
Because we don't have a complete skeleton of Spinosaurus and only partiel fossils, we can't fully see what the legs truly looked like, or how they might function.
Cope. But seriously. The length of the body alone makes bipedalism unrealistic. Even if we envision a set of walkers on Spinosaurus that could support its bodymass, it lacks the load bearing structures on its spinous process to support its lanky, frontheavy body. The protruding spines on the back weren't strong enough to support the body'a weight, and they don't have thr necessary muscle attackment points for the massive back muscles of the animal needed to hold up its head. The overall bodyplan of the animal would have to change DRASTICALLY for it to br bipedal, starting with the entire spinal column. This study just about confirms that the supposed scientists who are playing pingpong with Spinosaurus' anatomy, are either too incompetent, or too lazy to actually load the animal into a finite element analysis software.
@Horváth Benedek According to the most recent paper with a flesh model, even if it had lizard like airways (most mass in front of its body) its center of mass is over its legs and wouldn't require bipedal locomotion.
@@eewweeppkk I'm not sure I understand your comment - "wouldn't require bipedal locomotion" is a bit oxymoronic, since bipedalism is a tighter constraint here than quadrupedalism, so bipedalism can only be facilitated, not required. Regardless, center of balance is really the least of the issues. The elephant in the room is spinal rigidity. Even if the animal's massive tail would somehow balance its front-heavy front half, said front-heavy front half would need to be held up by massive backmuscles; and simply put, the animal lacks attachment points for these muscles. The vertebrae themselves are around half the diameter of similar sized theropods. Conversely, if you look at the size of the vertebrae of facultatively bipedal animals of similar size - mainly hadrosaurs -, you'll notice a distinct reduction in vertebrae robustness. It bears mentioning that these facultative bipeds also sported massively powerful spinous processes, something Spinosaurus ironically lacks.
Honestly this reminds me of when I was a kid and the old paleontology books I grew up on were all saying that Pteranodon was the largest thing that could ever have flown and it would have had a hard time getting off the ground at all. Or, if you go back to when my parents were kids, they grew up on sauropods being submerged in water to support their weight. I suspect that there are still either major problems in the skeletal reconstruction, or major issues with the way scientists are distributing the weight on their models.....or both. I suspect that, when all is said and done....this dinosaur will end up having proportions closer to the other Spinosaurids, maybe halfway in between what they're being reconstructed as now and something like Baryonyx. Certainly it could walk and it appears very well adapted for living at the water's edge, much like a stork. Storks are awkward too... This unending back and forth is what always happens when theories are devised with incomplete or incorrect data. Nothing is going to be settled until we find a definitive, well preserved Spino.
As someone who wants to write a (reasonably accurate) novel about the life of a Spinosaurus a la Big Al, every new piece of information is making artistic license look *very* appealing, you don't even know.
The short-legged model of Spinosaurus creates more questions than it answers. It did occur to me once that maybe it just dragged its belly along the ground and used its tiny hindlimbs to simply push it along, but the only other related animals known to occasionally move in this way are penguins. We have no evidence that any non-avian dinosaurs moved in this way.
makes me wonder if mud trudging could have been a viable means of locomotion. i also question it's sail being a solid sail and not just boney spines at this point, since another video i saw said if it flipped in water it couldnt flip back over lol. cant walk bipedal, cant SWIM, only thing i can think is it never left the shallows of the swamps/marshes and was simply a weird giant snaggle toothy mud fish that would crawl around and never have an opportunity to actually fall over on it's side in full depth water OR crush its own limbs trying to stand on land. would make sense to me tbh. it couldve used claws to trudge the mud, providing self locomotion thru marsh as well as dig up shit that lived under the mud, like turtles and frogs, and maybe soem prehistoric fish or worms or something we dont know about yet
It probably moved Like crocs. They also lay on their belly and move slowly.its weird how it looks like a crocodile yet everyone was like it's a 2 leg walking animal .made no sense apart from looking cool.you would think they would know something about evolution and subspecies and the tree of evolution .it doesn't make sense for spino to be bipedal its close related to crocs
Then 2130: just kidding turns out it was a really weird turtle, actually? 2160: well, you're not going to believe this but it might have been an arachnid.
Great insights! Thank you so much for sharing! Spinosaurus is literally a shapeshifter! Crazy how much it changes each year. 2050 Spinosaurus will be something else. :-)
Obviously spinos were seal-like beach dwellers, rapidly turning into dinosaur whales. It's the only logical conclusion that doesn't invoke another paleontologist war.
The idea of a hind leg reduced Spinosaurus tends to become more and more skeptic. Those that say otherwise tend to ignore the long list of issues it brings up. It's been in debate ever since the 2014 reconstruction been revealed. The current anatomy of Spinosaurus does make it the best swimmer and too big to move around on land. There are too many questions here than answers. Me and the paleo department in my faculty are starting to believe it's anatomy is similar to that of Baryonychinae (longer hindlegs) a good transition to terrestrial and aquatic lifestyle.
@@Deform-2024 Spinosaurus is an amalgamation of different fossils and fragments resulting in an error. The neotype might be from a single creature but it's incomplete and a juvenile. Plus it's far from the Egyptian dig site Stromer first discovered it.
I still have a feeling the spino is the bumble bee of prehistoric time. By our science bumble bees are to heavy to fly, specially with tiny wings, but they fly anyways.
Honestly, I can agree with you on that in terms of the Spinosaurus being the metaphoric, and quite literal, bumble bee of the Mesozoic (in terms of it's legs and other stuff talked about in terms of the Spino)
This video *PERFECTLY* explains the whole situation regarding Spinosaurus. There is no right answer about it or how it may have looked like. A few things are certain: It had dense robust bones and it was the largest theropod. More fossils and research is definitely needed for this enigmatic creature.
@@s_meekerorum Largest estimates always put Spinosaurus on top. We'll have to wait until the papers are released by Nizars crew. It's high bone density is already making it heavier than Tyrannosaurus
@@Jurassic_Gojira all 12 ton estimates are proven to be wrong, and the latest puts spino at eight tons max, while even an average rex would be heavier than that, and the bone density didn't change the weight estimates at all...
So first he can't swim, now he can't walk too? Than what did he do, sit on the shore where he was born with open Jaws waiting for a fish to jump in his mouth? Or rather, he slither his way around like a snake, oh but probably then people will say, nah to big to do that either, ofc.
You suggest that the image of spinosaurus, as of now, could be a Chimera. I honest agree. We don’t know how the sail is shaped, he don’t have a full image of the head, and as far as I know, the legs came from a different specimen entirely. Either two things has happened. One, the specimen including the legs and tail is a younger individual, which is unlikely, or, it’s a different species entirely as I said before. Look at all of spinosaurus’s relatives. They have had a normal theropod body to leg size proportion. Spino is the odd one, based on what we have as fact right now. If the legs and tail don’t go to Spino, then it must go to a relative, meaning Spino could have a similar tail, but longer more sturdy legs. I might be wrong, since I don’t know everything that has been discovered in each expedition since Stromer’s time. I can say this for sure though, Spino in my eyes could swim and it wasn’t a quadruped. Theropod’s had evolved to be that way, so why would this one animal out of a clade of bipedal animals be quadrupedal.
Those small limbs always convinced me that Spinosaurus is truly semi-aquatic animal like hippos. They probably able to walk on land to breed and do other stuff we don't know yet but sure as hell it wouldn't sustain them for long. I never understand the refutation against semi-aquatic because it has sail that's hindering their hydrodynamic. Like dude, have you seen reindeer antlers? They live in forest where they can stuck and getting them killed in the process but this doesn't stop sexual selection. The same could be the same for Spinosaurus.
Can't wait for the new spino (the crested one) that Sereno discovered to be revealed. Supposedly it has lots of other parts preserved. It will help us understand Spino itself a lot more. I still think there's something very wrong with the current models and the legs as you pointed in the video.
Think outside the box, it didn't move at all. It was an ambush fish-eater that would stay still in water and wiggle its tongue to attract fish. I'm just kidding, there is definitely a mystery here.
3029:Spinosaurs was an inyerdimensional god, while simultaneously beingas as heavy as abasilisk lizard its tail contained the necessary ingredients for controlling wind and its sail contained electrons to generate lightning storm.
Especially if it can't walk quadrupedally either so it's gotta be more or less bipedal and we just don't have enough spinos yet still to get a reliable answer like we do trexes
I honestly look at the Spino and see a gigantic river monster that spent nearly its entire life in water and went on land as a quadruped and resembled a synapsid like dimetrodon, but in water, had enough buoyancy to stand and hunch above the surface. I imagine it ate whatever it could find and spent a lot of time feeding off of living things at the bottom of whatever body of water it lived in, possibly digging for things in the mud. It was probably a very diverse environment.
The memes will never stop, *not* until we can definitely conclude what it looked like, how it moved, what's behavior was, and or all that, even then the memes won't stop.
Wasnt Mr Handerson as well as Mr Hone and Holtz already been shown that the center of gravity is closer to its hips and would be able to walk bipedally
@@Nigel_BC the aforementioned scientists although explained that it would be able to stand and walk bipedal within their respective papers earlier or beforehand I am not too sure the whole chimera fossil debates resurrection resurfaced the whole quadrupedal debacle I asked them within their accounts at social media hope to receive an answer soon
@@thedoruk6324 Very interesting stuff. I’m excited to see the direction that spinosaurus goes as paleontology advances. Honestly, I just want to know how the animal most likely lived and I don’t really care which way it ends up being.
@@Nigel_BC So do I. I really want to know current models are wrong or not as well as there are any second or third spinosaurinae species exist within the same habitat and timescale with the aegyptiacus or the whole 2014 or 2022 model must be re examined and throughly remade according to new findings
I think that another critical part of this equation is how much time did Spinosaurus spend fully or partially immersed in water which would lessen the demand on it's back legs for support. If tail size & shape estimates are accurate, it would seem that this animal spent much of it's time in water.
So is it possible that it spent most of its time in shallow water? Not deep enough to truly swim in, but enough water to support a lot of its weight? It could half swim half walk in chest deep water and hunt like a crocodilian
The bone density and size of the hollow centre seem to be a fixed but important clue that does not depend so much upon subjective assessment, lets hope a fuller single specimen turns up to solve all this.
People debating whether Spinosaurus could even walk due to its sheer size, yet at the same time, T-Rex is suddenly 50 feet long, weighs 20-30 tons and nobody bats an eye.
Unironically I saw one of those papers claiming tyrannosaurus was at least 10% larger than what we thought, I am definitely not understanding what is going on
@@mlggodzilla1567 I've heard people say T-Rex was 70 percent bigger than originally believed. And that's when I remember my Geology professor in college saying that all scientists were drunk.
I think that that particular study of the Tyrannosaurus was just like a possibility thing. If you look at humans for example, you will notice some are much taller and bigger in comparison to other people, so a Tyrannosaurus individual being (Slightly) larger than other members of the species, I wouldn't doubt it (not the 70% bigger than originally believed b/c that is absolute bogus and bs. I'd say like a small percent is more likely, like 10% or below that)
@@cooldinos8142 yeah fluctuations in that are common, for example average human height for a male is 5'9, but there are people that are 6'5 and above, so I wouldn't be surprised to find tyrannosaurus that were over 40 feet in lenght
i think that spinosaurus may have actually had longer legs than what we’re found because if we compare it to every other spinosaurid they all had constant theropod like posture and proportions and just seems outlandish to see a dinosaurs whole skeletal structure change for 1 single species now some people will say what about the sail well most other spinosaurids actually had sails but were very low like look at the suchomimus or icthyovenator skeleton. some other people could say that what was found was found and it was found that it had short legs there’s the possibility some leg bone fragments were lost and maybe that specific individual had some sort of genetic defect you see all in nature today some animals are born with shorter limbs that are purely by chance like munchkin limb deformity in cats or how some humans can be born with one leg much shorter than the other. i guess i could be in denial on how my favourite dinosaur was utterly ruined by new discoveries
Ah, no wonder there are Carcharodontosaurus bite marks on the spine. They were actually assisting their disabled Spino buddies to places like a real friend would do.
OMG Could it be that one day the spinosaurus will have an accurate body model? It's my favorite dinosaur and I can't even get a definitive picture of what it looks like in my mind.
remember that femur circumference isnt everything spinosaurus' femur was much denser than any of the dinosaurs in the analysis, I am certain it would make more sense if bone density was taken into consideration, please do this
I think we can just agree that Spinosaurus is just an interesting animal, and hopefully the newest bipedal-mostly aquatic recreation of the animal turns out to be the definitive version. This animal makes more sense that way.
if i got an opportunity to spend 5 minutes in total with a time machine to look at anything or anyone from any point of history, i would spend the whole 5 minutes staring at various spinos so we could finally settle down with something for good.
So the problem with using the 2014 paper to extrapolate it for Spinosaurus is that they measured the femur circumference, not taking cross sectional surface area into account. The varying thickness of the femur can result in a factor 2 or 3 difference, which is quite substantial. And although the cross-sectional area of most femurs is roughly circular, this isn't always the case, adding another error margin on top of it. I would like to see the results if they did a cross sectional area comparison instead.
I doubt that Spinosaurus was incapable of walking. If anything, the tail it not only helped with swimming, but also provide balance when walking bipedally. Spinosaurus was no slouch.
That I could see as possible, as the tail could help out with balancing itself whilst on land. And I certainly doubted that Spinosaurus would be incapable of walking on land, it's the same thing as saying bees couldn't, or shouldn't, fly because their wings are too small compared to the rest of the body (Just an analogy that reminded me of this situation with the Spinosaurus).
Maybe our boy was just a snapping turtle hippo hybrid, walking underwater and just vibing with it's tongue out until something got closer or until it needed to breath

I think it would be funny if in a few years after this whole time debating the anatomical nature of Spinosaurus, a perfect complete specimen is finally discovered and it turns out it always walked on two legs.
In fact it walk on 2 legs
Imagine if we find out that there are multiple species of Spino. One behaves like the Jp3 version (land based carnivore with shorter, sturdier snout and longer legs), one is basically the giant heron (semi-aquatic, medium sized legs, long snout, padded tail) and the other is practically a crocodile (very short sail, long snout, long paddle like tail)
@@quakethedoombringer tbh, I've always thought about this a lot when it comes to debating about Spinosaurus anatomy. It wouldn't be too farfetched either, we already have other Spinosaurids such as Suchomimus, Baryonyx, and Irritator so to have another species of Spinosaurus that it's bit more closely related to the actual Spinosaurus would be very exciting.
Like Tarbosaurus to Tyrannosurus.

We're going to keep having these back and forth, he said she said, debates until we can find a reasonably complete specimen that we are sure is ACTUALLY Spinosaurus instead of a hodgepodge of different specimens that may or may not be the same species or genus slapped together and roughly scaled to each other. It's becoming increasingly frustrating when you have a new paper coming out every week that is more or less going back and forth between the same arguments when we aren't even sure the reconstruction we have is particularly accurate. Things like this are what drives the public away from the science of these animals, when we should be doing everything in our power to draw them in.
If only that submarine wasnt destroyed long agooo, hope we find a full specimen, cause boy they do go back and forth with the Quad/Bipedal argument (unless proved otherwise,i always thought it was bipedal cause of the structure of its claws).
This back and forth though is part of what fascinates me about this creature. 🤓
this is the stuff that drew me in tho 🥰
The Stromer specimen being destroyed just feels like an inside job now. :(
Even *if* we find a fully complete fossil for the beast, we will still *not* be able end the debate.
The strangest part about the legs is that all of it's relatives have proportional legs. The tail just adds on top of the confusion to how such a thing could get around bipedially
see? its that reason that I'm convinced we found juvenile back legs, this whole thing just seems completely off, and the further down the Spino trail we have gone, the sadder this poor creature has become.
@@AckieGamer27same, those legs are definitely not from an adult
@@AckieGamer27 but they arent from a younger individual, the legs were from an animal similar in age, its been debunked long ago
@@TS-7864 similar age does not immediately correlate with similar size, is there no chance the specimen that the legs came from was malnourished or stunted in some way? think of the variance in every day animals, let alone humans, even if they're close in age
I was suspecting back then due to how different Spino looked compared to its supposed relatives, i thought it probably isn't in the same family as them. Imagine if Spino and Oxalaia get taken out from Spinosaurid family and the family gets renamed to Suchomimid
I feel like Spinosaurus will just continue to change every few years at this point.
Spinosaurus try not to have something radically changed about it for 5 seconds challenge (impossible)
for spinosaurus this was possible, just not for the scientists
I believe that Spinosaurus' sail was a Solar Panel used to power up it's propeller tail which it used both to travel in water like a boat and to fly in the air like the rotor of an helicopter
I hope they find a more complete specimen some day so we can have these answers. I yearn for them!
Everyone's favourite huge crocoduck platypus of the theropods has had been in so many changes, and it will keep going on as long as new wack stuff gets to be discussed everytime.
“Huge” this animal is just longer
thats what she said.
I’ve been making this kind of statement ever since 2014, and it’s nice to see some biomechanical research done on this. I literally never understood how an animal of this size could support it’s own mass with hind limbs that are smaller than it’s own arms.
doesn't make sense tbh
It also doesn't make sense for Spinosaurus to be quadrapedal either since its front limbs were not adapted to that kind of lifestyle. So, in the end, we just don't know. We can only wait until more Spinosaurus fossils are found.
@@BigAl2-u7e it walked Luke a seal
@@wingedhussar1453 he could hover in place
@@اسكندرفكارthey could *fly*
Because we don't have a complete skeleton of Spinosaurus and only partiel fossils, we can't fully see what the legs truly looked like, or how they might function.
Cope.
But seriously. The length of the body alone makes bipedalism unrealistic. Even if we envision a set of walkers on Spinosaurus that could support its bodymass, it lacks the load bearing structures on its spinous process to support its lanky, frontheavy body. The protruding spines on the back weren't strong enough to support the body'a weight, and they don't have thr necessary muscle attackment points for the massive back muscles of the animal needed to hold up its head.
The overall bodyplan of the animal would have to change DRASTICALLY for it to br bipedal, starting with the entire spinal column.
This study just about confirms that the supposed scientists who are playing pingpong with Spinosaurus' anatomy, are either too incompetent, or too lazy to actually load the animal into a finite element analysis software.
@Horváth Benedek According to the most recent paper with a flesh model, even if it had lizard like airways (most mass in front of its body) its center of mass is over its legs and wouldn't require bipedal locomotion.
@@eewweeppkk I'm not sure I understand your comment - "wouldn't require bipedal locomotion" is a bit oxymoronic, since bipedalism is a tighter constraint here than quadrupedalism, so bipedalism can only be facilitated, not required.
Regardless, center of balance is really the least of the issues. The elephant in the room is spinal rigidity. Even if the animal's massive tail would somehow balance its front-heavy front half, said front-heavy front half would need to be held up by massive backmuscles; and simply put, the animal lacks attachment points for these muscles. The vertebrae themselves are around half the diameter of similar sized theropods.
Conversely, if you look at the size of the vertebrae of facultatively bipedal animals of similar size - mainly hadrosaurs -, you'll notice a distinct reduction in vertebrae robustness.
It bears mentioning that these facultative bipeds also sported massively powerful spinous processes, something Spinosaurus ironically lacks.
Honestly this reminds me of when I was a kid and the old paleontology books I grew up on were all saying that Pteranodon was the largest thing that could ever have flown and it would have had a hard time getting off the ground at all. Or, if you go back to when my parents were kids, they grew up on sauropods being submerged in water to support their weight.
I suspect that there are still either major problems in the skeletal reconstruction, or major issues with the way scientists are distributing the weight on their models.....or both. I suspect that, when all is said and done....this dinosaur will end up having proportions closer to the other Spinosaurids, maybe halfway in between what they're being reconstructed as now and something like Baryonyx. Certainly it could walk and it appears very well adapted for living at the water's edge, much like a stork. Storks are awkward too...
This unending back and forth is what always happens when theories are devised with incomplete or incorrect data. Nothing is going to be settled until we find a definitive, well preserved Spino.
this channel has become like a spino-news channel and i'm so here for it slay✨️
As someone who wants to write a (reasonably accurate) novel about the life of a Spinosaurus a la Big Al, every new piece of information is making artistic license look *very* appealing, you don't even know.
The short-legged model of Spinosaurus creates more questions than it answers. It did occur to me once that maybe it just dragged its belly along the ground and used its tiny hindlimbs to simply push it along, but the only other related animals known to occasionally move in this way are penguins. We have no evidence that any non-avian dinosaurs moved in this way.
makes me wonder if mud trudging could have been a viable means of locomotion. i also question it's sail being a solid sail and not just boney spines at this point, since another video i saw said if it flipped in water it couldnt flip back over lol.
cant walk bipedal, cant SWIM, only thing i can think is it never left the shallows of the swamps/marshes and was simply a weird giant snaggle toothy mud fish that would crawl around and never have an opportunity to actually fall over on it's side in full depth water OR crush its own limbs trying to stand on land. would make sense to me tbh. it couldve used claws to trudge the mud, providing self locomotion thru marsh as well as dig up shit that lived under the mud, like turtles and frogs, and maybe soem prehistoric fish or worms or something we dont know about yet
It probably moved Like crocs. They also lay on their belly and move slowly.its weird how it looks like a crocodile yet everyone was like it's a 2 leg walking animal .made no sense apart from looking cool.you would think they would know something about evolution and subspecies and the tree of evolution .it doesn't make sense for spino to be bipedal its close related to crocs

@@sebastianaraneda8147 Completely agree! Excited to see what's next! :-)
It's never gonna end, eventually we're gonna get to the point that it turns out Spinosaurus could bend laws of space and time and had laser vision.
I wish I was like Beast Boy tbh: turn into any animal, living and extinct. So I can turn into a Spinosaurus and get these confusing debates behind us.
Obviously spinos were seal-like beach dwellers, rapidly turning into dinosaur whales. It's the only logical conclusion that doesn't invoke another paleontologist war.
The idea of a hind leg reduced Spinosaurus tends to become more and more skeptic. Those that say otherwise tend to ignore the long list of issues it brings up. It's been in debate ever since the 2014 reconstruction been revealed. The current anatomy of Spinosaurus does make it the best swimmer and too big to move around on land. There are too many questions here than answers. Me and the paleo department in my faculty are starting to believe it's anatomy is similar to that of Baryonychinae (longer hindlegs) a good transition to terrestrial and aquatic lifestyle.
I have no idea what you're trying to say here
@@Deform-2024 Spinosaurus is an amalgamation of different fossils and fragments resulting in an error. The neotype might be from a single creature but it's incomplete and a juvenile. Plus it's far from the Egyptian dig site Stromer first discovered it.
I still have a feeling the spino is the bumble bee of prehistoric time. By our science bumble bees are to heavy to fly, specially with tiny wings, but they fly anyways.
Honestly, I can agree with you on that in terms of the Spinosaurus being the metaphoric, and quite literal, bumble bee of the Mesozoic (in terms of it's legs and other stuff talked about in terms of the Spino)
That qoute about bumblebees is wrong, they absolutely have the body to fly
according to all known laws of ambulation...
I think they should try actually building a spinosaurus and see how it could move around
There was test conducted with the tail.
.. not a very good for swimming.
@@kelvinhernandez4714Maybe it probably used its legs for swimming, and its tail for balance on land.
This video *PERFECTLY* explains the whole situation regarding Spinosaurus. There is no right answer about it or how it may have looked like. A few things are certain: It had dense robust bones and it was the largest theropod. More fossils and research is definitely needed for this enigmatic creature.
Agreed 100%👆
i dont really see how its the largest theropod, and even if it was, it wouldnt be certain
@@s_meekerorum Largest estimates always put Spinosaurus on top. We'll have to wait until the papers are released by Nizars crew. It's high bone density is already making it heavier than Tyrannosaurus
@@Jurassic_Gojira all 12 ton estimates are proven to be wrong, and the latest puts spino at eight tons max, while even an average rex would be heavier than that, and the bone density didn't change the weight estimates at all...
Top 3 largest theropods are
1. T Rex - 11 tonnes
2. Giga - 9.63 tonnes &
3. Mapu - 9.12 tonnes
So first he can't swim, now he can't walk too? Than what did he do, sit on the shore where he was born with open Jaws waiting for a fish to jump in his mouth? Or rather, he slither his way around like a snake, oh but probably then people will say, nah to big to do that either, ofc.
You suggest that the image of spinosaurus, as of now, could be a Chimera. I honest agree. We don’t know how the sail is shaped, he don’t have a full image of the head, and as far as I know, the legs came from a different specimen entirely. Either two things has happened. One, the specimen including the legs and tail is a younger individual, which is unlikely, or, it’s a different species entirely as I said before. Look at all of spinosaurus’s relatives. They have had a normal theropod body to leg size proportion. Spino is the odd one, based on what we have as fact right now. If the legs and tail don’t go to Spino, then it must go to a relative, meaning Spino could have a similar tail, but longer more sturdy legs. I might be wrong, since I don’t know everything that has been discovered in each expedition since Stromer’s time. I can say this for sure though, Spino in my eyes could swim and it wasn’t a quadruped. Theropod’s had evolved to be that way, so why would this one animal out of a clade of bipedal animals be quadrupedal.
Did you even watch the video
Very believable analyse. It sounds like a far more likely theory than what creature we now have. And, well, usually the most likely theory is right.
You can call it a large 4 legged dragon with a sail
Isn't this the way they talked about "Brontosaurus" back in the day?
At least we're fairly sure Spinosaurus isn't gonna get declared invalid for a few decades. So glad my childhood fave exists again.
Those small limbs always convinced me that Spinosaurus is truly semi-aquatic animal like hippos. They probably able to walk on land to breed and do other stuff we don't know yet but sure as hell it wouldn't sustain them for long. I never understand the refutation against semi-aquatic because it has sail that's hindering their hydrodynamic. Like dude, have you seen reindeer antlers? They live in forest where they can stuck and getting them killed in the process but this doesn't stop sexual selection. The same could be the same for Spinosaurus.
How many changes do you want?
Spinosaurus: YES
Quantity
Can't wait for the new spino (the crested one) that Sereno discovered to be revealed. Supposedly it has lots of other parts preserved. It will help us understand Spino itself a lot more.
I still think there's something very wrong with the current models and the legs as you pointed in the video.
The Spinosaurus debate just never ends. Scientists really can’t decide what it really was.
so it cant swim, and it cant walk, HOW DID IT GET AROUND
Think outside the box, it didn't move at all. It was an ambush fish-eater that would stay still in water and wiggle its tongue to attract fish.
I'm just kidding, there is definitely a mystery here.
2027: Scientists discover that Spinosaurus had wheels.
3029:Spinosaurs was an inyerdimensional god, while simultaneously beingas as heavy as abasilisk lizard its tail contained the necessary ingredients for controlling wind and its sail contained electrons to generate lightning storm.
Yeah, it was GIANT DUCK. Learn this lesson: YOU NEVER GET IT RIGHT THE FIRST TIME!
Is that so? Fight the JP3 Spino!
Has anyone made a new model that addresses these issues? I just don't understand how we could rely on a model that literally can't walk or swim
Especially if it can't walk quadrupedally either so it's gotta be more or less bipedal and we just don't have enough spinos yet still to get a reliable answer like we do trexes
I honestly look at the Spino and see a gigantic river monster that spent nearly its entire life in water and went on land as a quadruped and resembled a synapsid like dimetrodon, but in water, had enough buoyancy to stand and hunch above the surface. I imagine it ate whatever it could find and spent a lot of time feeding off of living things at the bottom of whatever body of water it lived in, possibly digging for things in the mud. It was probably a very diverse environment.
Spinosaurus really is the platypus of the dinosaurs isn't it?
The memes will never stop, *not* until we can definitely conclude what it looked like, how it moved, what's behavior was, and or all that, even then the memes won't stop.
I hope in my lifetime that we eventually find the true look of Spinosaurus. It would pain me to not live to see that day come to be.
I fully expect Spinosaurus to either not have a sail or just pull a Troodon and no longer exist within the next few years lol
Dafuqs a troodon?
@Kakarot I can't tell if you're serious or not 🤔
The weight of Spinosaurus doesn’t make sense with its current reconstruction. Either we have the mass estimates way waaay off or it was quadrupedal.
The spinosausus weight estimated around only 7.4 tons compared to Tyrannosaurus rex weight estimated around 9-10 tons.
It's gonna be hilarious when it all circles back to Spinosaurus having a standard theropod body like the other Spinosaurids.
Ah yes another paper on the HeronHippoDimetrodonGorillaSaurus
"How long are Spinosaurus' legs?" "Not quite long enough to reach the ground."
Very short legs.
Only 2.2 meters long 😂much shorter than Rex's 3.9 meters long legs
Man Spino can't catch a break, our understanding of it has changed so many times over just a few years.
"Babe wake up, it's time for the 47th new description of spinosaurus this week!"
"....yes honey."
Wasnt Mr Handerson as well as Mr Hone and Holtz already been shown that the center of gravity is closer to its hips and would be able to walk bipedally
The femur isn’t built for it though
Didn’t someone relatively recently make a model that showed that its center of mass was too far forwards for it to walk bipedally?
@@Nigel_BC the aforementioned scientists although explained that it would be able to stand and walk bipedal within their respective papers earlier or beforehand I am not too sure the whole chimera fossil debates resurrection resurfaced the whole quadrupedal debacle I asked them within their accounts at social media hope to receive an answer soon
@@thedoruk6324 Very interesting stuff. I’m excited to see the direction that spinosaurus goes as paleontology advances. Honestly, I just want to know how the animal most likely lived and I don’t really care which way it ends up being.
@@Nigel_BC So do I. I really want to know current models are wrong or not as well as there are any second or third spinosaurinae species exist within the same habitat and timescale with the aegyptiacus or the whole 2014 or 2022 model must be re examined and throughly remade according to new findings
I think that another critical part of this equation is how much time did Spinosaurus spend fully or partially immersed in water which would lessen the demand on it's back legs for support. If tail size & shape estimates are accurate, it would seem that this animal spent much of it's time in water.
It would barely need to swim or walk if it stayed in water of the correct depth.
@@areyouavinalaff Agreed. It was probably a specific niche type predator and once that niche environment disappeared, so did poor old Spino.
So is it possible that it spent most of its time in shallow water? Not deep enough to truly swim in, but enough water to support a lot of its weight? It could half swim half walk in chest deep water and hunt like a crocodilian
Literally insane how often the interpretation of this fossil changes.
The bone density and size of the hollow centre seem to be a fixed but important clue that does not depend so much upon subjective assessment, lets hope a fuller single specimen turns up to solve all this.
People debating whether Spinosaurus could even walk due to its sheer size, yet at the same time, T-Rex is suddenly 50 feet long, weighs 20-30 tons and nobody bats an eye.
Unironically I saw one of those papers claiming tyrannosaurus was at least 10% larger than what we thought, I am definitely not understanding what is going on
@@mlggodzilla1567 the Tyrannosaurus rex was a TANK compared to spinosausus had a narrower flattened thin and slender body
@@mlggodzilla1567 I've heard people say T-Rex was 70 percent bigger than originally believed. And that's when I remember my Geology professor in college saying that all scientists were drunk.
I think that that particular study of the Tyrannosaurus was just like a possibility thing. If you look at humans for example, you will notice some are much taller and bigger in comparison to other people, so a Tyrannosaurus individual being (Slightly) larger than other members of the species, I wouldn't doubt it (not the 70% bigger than originally believed b/c that is absolute bogus and bs. I'd say like a small percent is more likely, like 10% or below that)
@@cooldinos8142 yeah fluctuations in that are common, for example average human height for a male is 5'9, but there are people that are 6'5 and above, so I wouldn't be surprised to find tyrannosaurus that were over 40 feet in lenght
i think that spinosaurus may have actually had longer legs than what we’re found because if we compare it to every other spinosaurid they all had constant theropod like posture and proportions and just seems outlandish to see a dinosaurs whole skeletal structure change for 1 single species now some people will say what about the sail well most other spinosaurids actually had sails but were very low like look at the suchomimus or icthyovenator skeleton. some other people could say that what was found was found and it was found that it had short legs there’s the possibility some leg bone fragments were lost and maybe that specific individual had some sort of genetic defect you see all in nature today some animals are born with shorter limbs that are purely by chance like munchkin limb deformity in cats or how some humans can be born with one leg much shorter than the other. i guess i could be in denial on how my favourite dinosaur was utterly ruined by new discoveries
Remindes me of a speculative evolution project where one animal inspired by spino, isnt able to return to the Land when it grows to its maximum size
Ah, no wonder there are Carcharodontosaurus bite marks on the spine. They were actually assisting their disabled Spino buddies to places like a real friend would do.

A day may come
When we find out how spinosaurus looked like
But it is not this day
I think we can just agree that Spinosaurus is just an interesting animal, and hopefully the newest bipedal-mostly aquatic recreation of the animal turns out to be the definitive version. This animal makes more sense that way.
if i got an opportunity to spend 5 minutes in total with a time machine to look at anything or anyone from any point of history, i would spend the whole 5 minutes staring at various spinos so we could finally settle down with something for good.
Obviously they floated around the air, the paddle tail was to navigate through the air
The next paper about spino will argue that the sail was a highly specialized wing, and Spino's are actually the first dinosaurs able to fly.
Spino is a cretaceous dino, birds had already taken over the skies by then.
@@bri1085taken to the skies, yeah, but pterosaurs still 'ruled' them
@@caffetiel no they forced pterosaurs out of the small flyer niche altogether. Save for the size limits birds have I don't think going too far here.
Spinosaurs probably just laughing at us right now as we are trying to figure it out for the longest 😂
Im really just thinking another dinosaur died in the same spot as the spino
So the problem with using the 2014 paper to extrapolate it for Spinosaurus is that they measured the femur circumference, not taking cross sectional surface area into account. The varying thickness of the femur can result in a factor 2 or 3 difference, which is quite substantial. And although the cross-sectional area of most femurs is roughly circular, this isn't always the case, adding another error margin on top of it. I would like to see the results if they did a cross sectional area comparison instead.
I doubt that Spinosaurus was incapable of walking. If anything, the tail it not only helped with swimming, but also provide balance when walking bipedally. Spinosaurus was no slouch.
That I could see as possible, as the tail could help out with balancing itself whilst on land. And I certainly doubted that Spinosaurus would be incapable of walking on land, it's the same thing as saying bees couldn't, or shouldn't, fly because their wings are too small compared to the rest of the body (Just an analogy that reminded me of this situation with the Spinosaurus).
Thanks a lot for keeping us in the loop!
