"we don't have as much of a tail as we would want" ah, the precious days of 2015, thinking that any part of Spinosaurus's body could possibly be normal.
Hehehehe……
We still don’t have the arms….
"We don't have as much of the tail as maybe we would want"
2020: "Allow me to introduce myself"
Yes indeed, this one already needs a small update.
@@stephenballard3759 small? Spinosaur has undergone a huge transformation.
If I was going to tell 2015 what's going to happen in 2020, I don't think I'd start with "We got a more complete Spinosaurus tail specimen."
@@MWSin1 I would. You don't lead with the bad news.
I came to the comments looking for this
I can only imagine how the paleontologists who discovered these dinosaurs would react if they saw how their dinosaurs actually looked like.
+Diego Amador I wonder the same thing! Mostly I think they'd be gratified to see how much workers can learn from a single specimen these days.
(That said, it's very rarely "what they actually looked like" so much as "what we know about them now, which might change next week.")
+Steven Bellettini well we know exactly what anchorins looked like
Imagine how William Buckland would react.
“Wait, these things were bipedal? They were fast and intelligent? They were BIRDS?! What the FUCK are you talking about?!”
I mean, can we even prove definitively that most dinosaurs weren't encased in a mucous membrane, like giant land slugs with vestigial skeletons beneath?
I know that's absurd, but, the point stands (slugs?) that soft tissue structures and such aren't very reliably built from skeletal remains alone.
I recall we found that bit of tail a few years ago, so, the slug hypothesis doesn't check out too well... but can you prove they didn't have turkey-gobblers?
@@aprinnyonbreak1290 yes haha yes we can. Just by looking at the bone structure you can tell how an animal moved, ate, and with information already known about it’s relatives one can therefore create a very well educated guess as to the recreation of the creature in its entirety.
How is this already outdated?!? I love spino, but it changes shape more often than an octopus.
new d&d monster: shape-shifting Spino-Octopus
I'm from the future and he's different again
Facts
The day Spinosaurus stops changing is the day the world ends
It’s even more outdated now.
Yesss! I've been waiting so long! I love all your videos
What?
Trey watches this?
Makes sense I guess, pretty much your video.
Dimetrodon though, still bugs me that it hasn't been updated.
+XmasPig We'll revisit _Dimetrodon_ when/if we ever go back to the Permian period; until then, as long as folk absorb that it ain't a Dinosaur, I'm happy. Thanks for watching!
+Steven Bellettini Yay, that's perfect.
+Steven Bellettini Please do carnotaurus because I don't feel like there are a lot of clearly accurate depictions to give a good image.
+XmasPig I just made a dubble comment :(.
TH-cam comment loading is so broken, I've reloades them multiple times now and every time some comments don't show up.
6:45 "We don't have as much of the tail as maybe we would want"
Laughs in 2020.
'and i made myself sad, coz i'll never get to do that' 16:41
😂
I thought the same thing till he mentioned it.
let's just.. revive the goddamn Spinosaurus so he could do that, protecc his smile we must..
Ark: Survival Evolved is a thing now
Makes sense
You should do a part 2 now that we have more info on the tail especially
and the whole knuckle-walking thing
@@maddox2261 yeah now the quadropidal Spinosaurus is inaccurate
They are doing reuploads and updates on their channel
It's absolutely insane how much our picture of Spinosaurus has changed recently. Might be more dramatic than any other dinosaur discovered so far
You should do "your dinosaurs are wrong was WRONG" episode for spinosaurus. I bet all of us would love to see it after all the news we got since this episode came out.
The joke is that this could be a monthly, if not a weekly content😂😂😂
I always looked at Spinosaurus and I always said "He must be a great swimmer."
You. The big brain.
He is a great swimmer. He has a tail like a fish
3 years later, and the latest spino find has validated your hunch.
No
And your right!
You should revisit the spino with the recent updates on the tail shape and all
The new spinosaurus is like a pelican, crocodile, dinosaur hybrid
And I love it
And to make them even more crocodile like, crocodiles are one of the only other animal to have pressure sensors on such a pattern or place
Gharial not croc.
But like the guy says in the video, that's way cooler. Aquatic and spiny dinosaurs are beast.
@@kylefrank638 it has been discovered that occasionally it could eat some pterosaurs too if I'm not mistaken
I detest it
6:44 They found the tail, and it's an aquatic adaptation! Just a few weeks ago, a study was released about a new, more complete Spinosaurus fossil they just found. The neural spines on the caudal vertebrae (the bit that sticks upward out of the tail bones) are really tall, so we now think it had a finned, eel-like tail that it used for swimming.
th-cam.com/video/fDhofM81RQE/w-d-xo.html
the shape of the sail probably varied in bone structure, meaning each sail of an individual spinosaur was different.
+quenton dolejsi How much so, though?
Steven Bellettini I think of it as fingerprints, very small differences. Like maybe 5-6 small bumps on one and like 9 on another
Not much support for that
#LogicPaleontology
It could have also changed with age as well. Not to say that it did, but it's possible
And then came 2021, and Spinosaurus is a fierce stork (minus the flying and the babies)
Spino is my favourite dinosaur because he always finds a way to get even weirder to confuse scientists, in just 6 years he's yet again completely different
This year spinosaurus got EVEN weirder. As if it could.
'Other dinosaurs are too scared to be as weird as spinosaurus'
*Deinocheirus stepping into the ring*
‘We don’t have as much of the tail as maybe we would want’
Honestly the discovery of the fin like tail has made me so happy, the more we can learn about dinosaurs the better!!!
I love how your enthusiasm seeps through even though you're trying to look like a super serious biology professor.
I'm just waiting for the follow-up episode describing the new gigantic paddle tail
Spinosaurus has always been my favorite dinosaur ever since I saw Jurassic Park III as a kid. In recent years, I've found that the increasing information we've found about Spinosaurus makes me love it even more.
Not bad. Notice how the final model still stands its hind legs. It probably could move bipedally. Maybe not as well as other theropods, but it could still manage. It probably switched from standing on all fours and bipedally depending on what the situation required. I'd also like to say that, since this video was released, Spinosaurus has only gotten weirder. A new study this year now suggests that it's jaws were far more flexible than that of other theropods, and were similar in some ways to those of Pelicans and snakes, enabling them to stretch their jaws wide enough to swallow even small dinosaurs whole. This thing really was a freak of nature, which is why it remains my favorite dinosaur.
Spino has been my favorite since JP3. Knowing that one was super wrong and seeing how it really looked just makes it even cooler to me.
My idea is that the Spino would certainly need a partially quadrupedal posture for its piscivorous diet. It would need to bend down a lot, which would be absolutely hellish for a front-heavy animal like the Spino, so it would use its arms to hold itself up.
I think it stood up like a bear or meerkat balancing on its tail but not for long because of its weight
Megalodon
Exactly
@@a.morphous66 That's why the Sereno work is still controversial to this day. It is extremely difficult for an animal like Spinosaurus to be quadrupedal, given how they forearems are clearly not adapted for supporting its mass.
"We don't have as much of the tail as maybe we would want-"
just wait, past-Steven. 2020's got a gift for you.
2020: no, thats wrong tail
Difficult to talk about a discover before we did it!
lol
2020: no, thats wrong sail also maybe possibly
it was not all wrong just the tail and the theories on balance.
Most recently they’ve deduced Spinosaurus fed like a giant stork.
PLEASE do a Spino update!
I love what people say about the new study.
For every other discovery: "Oh cool."
A discovery that changes a fundamental thing about our knowledge of that dinosaur/dinosaurs altogether: "That seems pretty shady and ridiculous. I don't think it's true."
What do you mean with new study? The 2014 that proofs that is was quadrupedal or the newer ones disproving that?
Dem Markus sein Profil It's still pretty new, considering paleontology has been around for hundreds of years.
5raptorboy1 Yes, but what did you mean? That was the question.
Dem Markus sein Profil The quadruped study, sorry for being a bit confusing.
5raptorboy1 Ahh, ok. I personally didn't care about that although I just can't imagine how in a family that is entirely bipedal, a quadruped just pops out of nowhere. I mean Evolution is just awesome, but all close relatives like suchomimus were biped so I was really confused at that time. That's why I personally still don't really belive it. Also the newer studies are a bit more convincing for me. But it really is sad how pop-culture made people blind about these animals. No one wants to accept that most of these were feathered :(
2021: This video needs to be renamed MDAW (My Dinosaurs Are Wrong).
I'd really like to see an update.
new Spino is still cool but in a different way.
I try to imagine what reactions would the XIX and early XX century paleontologists would have if they saw how "their dinosaus" would actually look like.
Hopefully awe
Felipe Andrade I’m hoping they won’t act like all those Jurassic Park fanboys claiming that the new discoveries have “ruined their childhoods” or in their case “ruined their work”.
So cool that this is already out of date, spinosaurus gets more badass every year!
I think the game ARK Survival Evolved should be looked at in this series. Not necessarily to criticize their lesser depictions (ie: the Dilos right out of Jurassic Park) rather to look at their oddly accurate ones (Trike, Spinosaurus, Utahraptor, etc) Plus in this context you'd get to go over actual locomotion.
If you need to be happy again, speaking of that game, it supports Virtual reality and you can tame and ride most dinosaurs including the Spinosaur. You can't feel the touch, but you can get crazy close.
Also I'd love to see someone with Paleo cred criticize their Theropod hands always facing down :-D
+Stereo3DProductions What's accurate about the Triceratops with Styracosaurus head gear, elephant legs with turtle feet and gigantic tail of out the early 1900s? or what's accurate about that broken-wristed Jurassic Park 3 copycat of a raptor with that half-assed feathering?
The Spinosaurus, gets the overall body plan right, proportions and details wrong... which is no better than what can be said for even their worst models.
+Stereo3DProductions Lol sauropod sized Giganotosaurus.
Fang Lee
My worst fear is when they finally put in the Oviraptor. Looks like a gecko with a beak. Heck, their "Dodorex" mock creature looks more like an Oviraptor than their Oviraptor.
They get carried away here and there, but with the bar so low in pop culture depictions of dinos, I feel this game has paid a welcome attention to accuracy, as little as it may be. Heck the last Jurassic Park movie jumped the shark in comparison!
Stereo3DProductions Dodo rex just felt kind of unreasonable to be in tbh...but they did mention they'll begin to take the fantasy route now. I don't know, I just don't understand why they'd go so far to make accurate dinosaurs to unrealistic dinosaurs.
However like you said, they did at least welcome accurate depictions. So that is a plus...
And no kidding, that mosasaurus and shark weren't their actual size. The shark should've been bigger and the mosasaurus should've been smaller. Oh well, can't deny it wasn't entertaining (for me at least).
The ones you named are really inaccurate. But they aldo have spiky JPish Dilos, plesiosaurs with horn-claw-armor thingies on their faces, 5 story tall mammooths with 4 spiky fangs (or what those things were), a titanoboa with a frill, and so much more.
This is such a weird animal. So much of it doesn't make sense when you think about it in terms of it being on land, and with the new information basically making it a pelican alligator is just crazy to imagine.
I've been playing a lot of jurassic world evolution lately and I think it would have been much cooler if they had gone with this more accurate spinosaurus instead of the classic Jurassic park spinosaurus. It's got a lot of bright color on the crest and it's very pretty but it's like you said where it's just t-rex with longer arms and a funky back.
At the time this was made, I am so, SO glad they didn't use the quadrupedal Spinosaurus position, which is now outdated.
Spinosaurus went from a big trex with a spine to a giant crocodile mixed with a duck
LOVE LOVE LOVE IT! Huge fan of the archive series! love to see the changes throughout time as new discoveries are made! Would love to see a Spinosaurus archive episode, since so much has changed since that video was made!
6:45
And now we do. I love how we keep updating the spinosaurus (and dinosaurs in general) with new and new findings. It's like a never ending journey :)
The year is 2105, and paleontologists now know that Spinosaurus was a flying filter feeder. With laser vision.
Can’t wait until this gets reuploaded on the new channel and gets updated!
I feel like this needs to be revisited! We now have more of the tail!
Imagine a Spinosaurus swim tranquil in this posture on a Lake.
No imagine a Spinosaurus with Feathers.
Now you have a really big Duck.
I've seen people sat, 'but feathers would hinder it in the water'... yeah... let's pretend penguins, swans, ducks, gulls, grebes, coots, moorhens, etc don't exist and have feathers that benefit them.
Like the claim feathers would cause parasites... yeah... they did... big ones. Modern birds get little ones at least.
All pretty stupid.
New Spinosaurus, a badass super crocodilian, makes a lot more sense and I find it much more interesting than the skinny t-rex theropod of old. The s-curve spine seems like it'd be exceptionally good at lunging forward, kind of like an egret, and the posture even makes a lot more sense as I'd imagine it dragging its belly like a crocodilian in most cases. All things considered behaving more like a crocodile makes its most distinctive feature seem perfectly sensible! I only wish I could see the real deal in action.
And now there's even more weirdness about spinosaurus 😂
Spinosaurus: " I'm the biggest, most scary looking carnivorous dinosaur ever!"
Me: "So what do you eat, big sauropods?"
Spinosaurus: "No, um....fish...."
Seems like they fill the same general niche as a bear. It moved mostly on all fours and could rear up on their hind legs and even walk around like that for a while, but their not dexterous that way
moukidelmar More like a crocodile. Eating mostly fish.
I don't think it was that flexible
Spinosauridae in general, along with Abelisauridae, contain my favourite prehistoric dinosaurs. I love how convergent evolution just looks at a Spinosaurus, then later looks at a pelican and goes: yeah, different but the same.
I really love these softer, more round restorations, makes them look like actual animals.
I'd love to see a carnotaurus
Carnotaurus would be great!
Yes. Carno please
I love carnotaurus!
+Your Best Friend I SENT them a Carnotaurus....
Henry Reed YAY
it is SO cool watching this is 2020, KNOWING about the paddle-like tail, because i LOVE to see how our understanding of dinosaurs has moved on in such a short amount of time! it straight up makes me giddy.
The knuckles are too frail to walk on; they'd break. His legs were long enough to walk on but still shorter than the other therapods. He definitely couldn't walk on all fours tho!
16:40 also he is so freakin cute hahah
It's now revealed it had a swimming tail so it probably wouldn't have to walk on it's legs that much
Really great talk on Spinosaurus which is one of my favorite dinosaurs and Steve is one of my favorite speakers on dinosaurs. Great job!
once I saw that figure I thought EVERYTHING ABOUT THAT IS WRONG lol
Steven: We don’t have much of the tail
5 years later: H E T R I E D I T
It would be awesome to see an amended version of this sometime. I understand that the recent discovery by Ibrahim, et al. didn’t blow up our entire notion of Spinosaurus (which would “necessitate” a much more in-depth breakdown on Steven’s part), but rather confirmed what many of us had long suspected, but nonetheless, I would enjoy hearing Steven geek out about it.
2023: "Wings...apparently it could walk, swim and fly"
They've revised it again, and come to the conclusion that Spinosaurus was likely bipedal. Which makes a lot more sense, for various reasons. The biggest reason among them being, not a single relative of Spinosaurus is a quadruped.
This is me at Thanksgiving dinner talking about dinosaurs my family doesn't care about, getting more and more excited with each breakthrough and fact I mention.
Did other spinosaurids live the same way? Did Baryonyx have webbed feet and walk on all fours and have pressure sensors in its snout?
Who knows? Except I think we found a full skeleton
HaraPlaysYT 14:00
HaraPlaysYT nope
HaraPlaysYT spinosaurids were piscivores and they probably did have webbed feet and sensors like crocodilers i dunno about baryonx but its highly possible that spinosaurus was a quadraped dinosaur and a semi aquatic creature so webbed feet and sensors also was a thing
HaraPlaysYT spino is not the giant beast you saw on jurassic park 3 stop thinking like that
Now you need to do a Your Dinosaurs are wrong of this episode, :)
this spinosaurus looks so much cooler than the bipedal spinosaurus
IKR!!!!!!!!!
Finally someone agrees with me
isn't the 4 legged spino debunked? still agree though that this one looks better than both biped and 4 legged.
+MrTianlp where has this been debunked at?
Gas Attack well not debunked, more like under debate.
the biped spino ain't good looking, nor does the quadruple one,
But the short biped one makes the most sense.
Finally!!! Just a layman, but I was NEVER able to buy the upright posture. This makes sense. And diminished in stature?? Put your mind back a few years: you're on it's back, next to it's sail as it cruises the swamp. That size, that head, those claws and teeth... If it never got off it's belly, this would still be one of the Scary Monsters of all time.
Great video!!!
You need to revisit the Spinosaur because new evidence has shown the tail has much more verticality than research in the last thought.
I also am wondering if the Spinosaur could have been mostly aquatic, split between swimming in deeper waters, and wading through shallows, while rarely visiting land? Maybe that's totally wrong though.
And then came 2020. Spinosaurus partially evolved to throw scientists for a loop, I'm sure, but I love it so much!
5 years later: "Oh no..."
Spinosaurus got updated yet again and now this is on my recommended
0:43 OMG I'm there! :D
lol! I was surprised too!!!
+BionicleSaurus I noticed you, Cool to see how much you love this science
;)
BionicleSaurus I love your channel!
I saw you too
Wew!
6:39 "We don't have much of the tail as maybe we would want"
It's Always Sunny in the Cretaceous
This video requires a Follow-Up.
Imagine if we went back in time and the dinosaurs looked EXACTLY like the very first reconstructions, that would be hilarious
Spinosaurus needs an update again.
I used to think spinos were so boring because they were basically just "trex + sail" in toys and media, so I never looked into it. I can't believe I ever bought into that lmao, but I'm so glad paleontology is progressing smoothly and we're getting better ideas of how these amazing creatures might have looked.
Apparently a new study found that due the Chimera nature of the Spino model uses....they accidentally missed-sized the hind legs in according to the other bones used.
The rear legs need to be a out 27% bigger.
Giving Spino better capability to walk on it's hind legs like a standard Carnivore.
BUT it could still walk on 4 legs like some aquatic herbivores.
Would be useful in shallow water and fishing!
equarg So it couldn't swim? If so that's a bit of a downer :(
who said it couldn't swim its legs are just a bit longer so it would be awkward /difficult to do a quadrupedal stance
That's already proven to be wrong. The authors of the 2014 paper replied and showed what made the confusion possible. The legs aren't 27% longer, the original 2014 paper was right after all.
There's nothing the suggest it walked on four legs. What we have of its front limbs and shoulder blade suggest nothing of it being capable of this. Also a new paper from 2016 showed that it wasn't too front heavy which was the argument the authors of the 2014 paper used to suggest it had to walk on all fours.
Robin Liesens it probably can walk on its back legs but can't run
Now this is due for a remake! Maybe have Basilosaurus be the anachronistic adversary instead of Tyrannosaurus?
suggestions for your dinosaurs are wrong: monolophosaurus, carnotaurus, orlorotitan, sinorinithosaurus, carcharodontosaurus, and giganotosaurus
Yes!!!
Add in the dire wolf. He could have an opportunity to roast Game of Thrones Season 8.
I know this was before the study about Spinosaurus having a tail sail, but I'm surprised it wasn't even raised as a possibility even though ichthyovenator is shown with a tail sail while bearing a less prominent sail overall.
I saw the PBS documentary on the reconstruction and found it really interesting. I will admit to being a bit dubious about the 2014 reconstruction. I guess I feel there's no precedent, exactly? Every other theropod, including closely related species like Baryonyx, walks on two legs. I would really like to know more information on a Spinosaurus's hips, because it seems awfully extreme to me that this gigantic creature is the only one who made such adaptations, despite having physiology (bones) that overwhelmingly point to it being bipedal. Now, granted, it could well be that Spino being reconstructed like this means its brethren will get a similar overhaul and we will see quadrupedal Baryonyx and the like. Knuckle-walking also strikes me as a little far-fetched; usually there is reinforcement for such mechanisms (like Megatherium's magnificently fused radius and ulna), and the Spino's elegant foreclaws seem better suited to grabbing and holding down fish to assist the jaws.
I just can't think of any other example on the Tree of Life where the broad strokes are there, but something is fundamentally reversed about the physiology.
I'm not opposed to it on grounds of vanity or anything, but it just seems to stick out too much to me. It's too different. But I'd like to hear any rebuttals to my concerns. Your video certainly made an excellent argument for how such an animal not only could have lived but thrived.
It seems that currently spinosaurus is tilting between bidedalism and quadrupedalism in the paleontological discussion, as it might have in life. I think the most recent consensus is that it was probably bipedal, but I'm not completely up to date either.
"The Spinosaurus fandom scares the shit outta me." --Lindsay Nikole
While perhaps not 100% accurate, you can ride a Spino in Ark: Survival Evolved. :) They're all kinds of fun, and really great swimmers. :) I'd suggest you give it a try, if only to enjoy all the well rendered creatures.
"Spinosaurus isn't as cool now that it's turned out to be aquatic."
Crocodilians: Are we a joke to you?
Of the Megalosaurians, I think Spinosaurus aegyptiacus is my favorite!
You should do an episode on how spino was too big to walk and what that means for future reconstructions
Spinosaurus is my favorite animal that ever lived! :)
The Poke'Saurus SAME
Same
"Enormous aquatic hyper-carnivore" is way better than "T. rex with a sail"
To me, the new spinosaurus looks bad ass
When they extended the rib-cage, I giggled. By the time we got to the eyes moving, I was full-on laugh-crying. She's absurd and I love her.
I find kinda hard to believe that no one has ever suggested that spinosaurus's jaws and the mouth of a salmon look so much alike.
cant wait for the revisiting episode
It's so weird how birds are technically ornithischian (bird hipped) by definition, but actually descended from the saurischian (lizard hipped) side of the family tree of dinosaurs.
"We don't have as much of the tail as we want"
well that didn't help
weren't the legs of spinosaurus discovered to belong to a different species, and should be 27% larger ?
The rebuttal says no.
what?
Jeffrey Gao What?
James Cootsona yeah there are more than one spinosaurus
it was of a different specimen, same species and the specimen for the rear legs were of a smaller specimen.. it was an obligate biped on land, its hands were incapable of facing palm down and its knuckles were not reinforced enough to bear its weight
I'm just imagining this thing as a gigantic goose. Think about it, curvy neck, aquatic, basically a bird already.
This is cool! You do any creature? How about Machairodus?
I love that I discovered this in 2021... just need an update to this video
Oh dear this video didn’t age well, now you’re dinosaur is wrong
Your*
so it was up to date with the most recent fossils that time when it got uploaded, besides a video update for Spinosaurus should be an order already
I've only watched two episodes so far and I'm in love with this series. Keep up the awesome work
I request the dinosaur from the opening. What the heck is that thing? I really want to know.
It's a Beardasaurus Mustachionerus, duh.
It’s so cool to hear about this and his comments on the tail knowing what we do now
I think it's far more fascinating to find it's a semi-aquatic creature, filling a niche something on the par with a crocodile. philogenically, how do they relate to something like the pliosaurs or mosasaurs??
The exact relationship between the major saurian lineages is kinda poorly resolved, but the animals you named were very distant: Pliosaurs & Mosasaurs were more closely related to each other, and to modern turtles & snakes, respectively, than they were to the dinosaurs.
6:45 “We don’t have as much as the tail as we want.”
2020 discovery: Are you sure about that?
