Acrocanthosaurus | The King of Early Cretaceous North America

- เผยแพร่เมื่อ 21 ก.ย. 2024
- When you think, North America and giant carnivores, the T. rex is almost certainly going to be the first dinosaur that comes to mind. However, millions of years before the legend itself, another theropod was ruling North America, and it wasn’t even a Tyrannosaur! It was the Acrocanthosaurus. It was an apex predator that dominated the lands and had a knack for going after armored Ankylosaurs and even massive sauropods, taking on the likes of Astrodon and possibly the Sauroposeidon .

Acrocanthosaurus is such a formidable predator. I feel like the only reason why it isn't more popular is because the name doesn't role off the tongue as well as T.Rex, Giga, and Spinosaurus.
Giga and Spino were only popular because they competed for largest carnivor. Otherwise they would have remained in the same spot many others compared to T Rex. But I do agree this Dino is cool. I seen one at a museum once. It was the star attraction at that museum. I also have a decent replica in my dino collection set of replicas.
They need a good PR blitz. Something like 'Yes Acro CAN!'
Acro rolls off pretty good and is awesome in the game The Isle.
@Planet Dee There seems to be a misconception that the Giga was a competitor in size with the T.Rex. The Giga was long and narrow, making it light weight. The Giga's skeleton, including the skull, is less robust than T.Rex. Everything we know about T.Rex suggests it killed anything in its path. To include Rivals. The Giga most likely hunted in groups and was not nearly as aggressive. Both predators are very close in length. The Giga has been measured at 43 ft long while the Tyrannosaurus measured in at 40.5 ft. It's hard to imagine such a robust creature like T.Rex weighing less.
@@PyroBlonde7777 True. Most information goes hand and hand with the idea T Rex was larger as far as weight goes. In addition, as much as I love JP T-Rex, it was slim with no gut. Now modern interpretation shows it with a huge belly which makes sense and increases his mass. Also making him much more vulnerable to his rival, the triceratops.
It's amazing to think that of the almost 80 million years that was the Cretaceous period, the iconic T.Rex only existed for a few million years at the very end.
@@kyachdistent1301 Yes because the T rex is to blame for it's own extinction and it had nothing to do with unlucky timing of a huge extinction event including a giant ass meteor hitting the earth.. How is T rex supposed to deal with that exactly? It's not being inferior that got it killed. It's bad luck. Also Humans have yet to make it to 1 million years and we seem well on our way to be unable to stop our own extinction as well. The T rex had some excuses, things happening outside their power. Meanwhile we are responsible for starting up the very things that will likely kill us unless we get our act together real real quick. T-Rex was fine. I am not saying better or worse then other dinosaurs because I am facinated by all of them. But the attitude around a dino being more or less great depending on how long they managed to live is dumb. T-Rex could very well still be around if it where not for certain events outside of it's control.
@@kyachdistent1301 Oh come on... NOBODY could have survived that asteroide. Your old favourites included. We will never know all the millions of years T Rex could have thrived were it not for planetary disaster. I'm even saying this as a Spino fan... It's about being something called Reasonable. T Rex was definitely Great.
@@kyachdistent1301 Dude, did you forget T-rex went extinct because of a cataclysmic event that pretty much wiped out ALL dinosaurs? Considering the fact that we have more a lot more complete T-rex specimens than basically any other theropod on record is indicative of how successful T-rex was as a species in terms of population density. The only North American theropod that could rival T-rex in that regard was Allosaurus.
@@kyachdistent1301 dumb comment
@@kyachdistent1301 dumb
Probably my favorite giant theropod dinosaur. Everyone jumps to T. Rex when it comes to giant dinosaur predators but the hump on Acrocanthosaurus made it unmistakably unique--kind of the best of both worlds from Spinosaurus and T. Rex. Glad to see it finally getting some love!
Ceratosaurus is mine.
Good comment. I'm sure it got more fish than Trex, but loved red meat. Now I'm hungry !
As you see spino is mine although it isn’t much of a agile or strong predator but one of the most unique dinos.
Spinosaurus was a real-life dragon though. Obviously it didn't fly or breathe fire but physically, it's resemblance to mythical dragons is insanely close. If you took someone from the Middle Ages and told them you were going to show them an actual dragon and brought them to a tied-up spinosaurus, they would not be disappointed.
Spino is my favorite but acro is next in line
Acrocanthosaurus deserve to be in a Jurassic Movie or any other Dino movie. It’s so underrated, it’d be a great main threat to a Dino movie.
As an Arco enjoyer I agree
It appears in jurassic park operation genesis unfortunately finding a copy of that game and a computer to run it may prove difficult. It had impressive graphics for the time period it came out though.
@@brianzulauf2974internet archive is your friend my guy
Acrocanthosaurus definitely does deserve more spotlight as well as my top favourite carnivorous dinosaur “Carcharodontosaurus” meaning “Shark-Toothed or Jagged-Toothed Lizard” though I mainly stick with shark-toothed because it’s named after the scientific name for great white shark “Carcharodon Carcharias”.
its funny in a perfect canon world i'd have the giga in dominion be known as an acrocanthosaurus instead because of the long spinal spikes and the fact it resembles that more than a giga and the fact it bumped into a t rex in the prologue! if it had to be giga in current day at least, then have its dna be part acro to fill in the gaps and explain the dorsal situation.
It must be remembered that tyrannosaurs only became large predators at the very end of the Cretaceous. Beforehand they lived in the shadow of Utahraptor, Acrocanthosaurus and Siats.
Well if you wamt to go into the Jurrassic, it'd be easier and more helful to say that carnosaur therepods(allosaurids and megalasaurids) ruled the world for around 80 million years. Whilst tyrannosaurids (with the exception of Yutyrannus) were large predators for barely 30 million years.
But yes stokesosaurus, a small tyrannosaurid. Was found in the morrison.
I think, this is exactly why Acrocanthosaurus went extinct. Prey items are getting incredibly more dangerous as opposed to just being a simple hadrosaurus where all you need was to chase and bite it's neck. You got new ankylosaurid which had thicker armor and heavier clubbing tail. Ceratopsid that literally grow horns up to 1.5 meters. Sauropods that were getting rarer also much more aggressive and protective on their offspring. Mid-late to late cretaceous produce enough "Alien" like dinosaur that carcharodontosaurid like Acrocanthosaurus were not built against.
You need a new apex predator that can handle these new dangerous prey items, a Theropod that had the power to break ceratopsid horns and crush the armor of Ankylosaurid. A new predator that can survive a full blow of ankylosaurid tail on it's face. A new Predator that can survive an injury of being impaled by a Ceratopsid horn. T-rex had everything evolution wants.
Evolution determines the next top predator and it happens that T-Rex had everything it fits for the new, more violent environment.
Edit : intriguing how environment gives more difficult prey items and then they also created T-Rex as a solution to it, then selectively removed carcharodontosaurid in the process. It's just a better designed killer for a new era with much fitting tool.
You are forgetting a little thing called the *CENOMANIAN-TUROIAN MASS EXTINCTION.* where all the carnosaurian predators went extinct, (and meso predators like tyrannosaurids, megaraptora s and abelisaurs globally moved into their niches) along with the rebbahisaurids sauropods and some other groups. It is also only after this event that you get those herbivores you speak of. And you don't really get them outside Asia and America. Also acrocanthosaurus shared its habitat with big and robust and armed iguanadonts. You are also forgetting that Tyrannosaurus only is one of many tyrannosaur of many a d most, like Lythronax, albertasaurus, gorgosauris, daspletetosaurus, and even the bigger eastern appilachisaurus were all SMALLER and lighter than Acrocanthosaurus, and they survived in enviroments filled with ankylosaurs ceratopsians and big chonky hadrosaurs.
So yeah i do not think acrocanthosaurus would struggle if it were suddenly thrust into the hell creek formation in place of tyrannosaurus. Any time before the evolution of tyrannosaurus (tarbosaurus and Zuchengtyrannus as well)itself acrocanthosaurus would easily be the most dominant predator on the continent. Probably the world at that stage as abelisaurs were never very impressive and the only comparable giant megaraptoran we have, maip, is also at the end of the Maastrichian. We don't have evidence in the cenomanian for acrocanthosaurus anyway. That is why i said Siats. Acro seems to have been in the Aptian and Albian, so it was still present for a good 20 million years, possibly more but we don't have good evidence for earlier asside from trackways.
Siats is a bit smaller and lighter than acro, probably more allosaurian but everything i said applies still to Siats. Its a heavier predator than Appilachasaurus- the largest Campainian
Tyrannosaurid.
You're basically just focusing on the last few million years of Tyrannosaur evolution when they got huge. These animals are not typical of rhe family. They were, as therepod families go in size, pretty mediocre before the latest eras of the Maastrichtian. And alas they died before their time.
@@islamicschoolofmemestudies best analysis i heard of when comparing tyranosaurus to gigaoto and acrocanthosaurus !
I saw a skeletal reconstruction of one of these next to a Trex in a museum in Texas and it was formidable, terrifying even. Unlike trex, this animal had slicing teeth and massive claws attached to robust powerful arms.
This animal would grab large, even massive prey with it's powerful claws, put it's massive weight and power on to the prey, while it's jaws sliced through flesh like butter. It's teeth were serrated, reminds me of great white shark teeth, it would slive through flesh very easily.
Carcaradontosaurus usually had these flesh slicing teeth, maybe this is what triggered large animals too big to run fast to evolve armored skin. Early tyranosaurids also had slicing teeth but as armored dinosaurs proliferated, tyranosaurids evolved more robust teeth and more powerful jaws, they also gave up on claws. An interesting example of arms race in nature between predator and prey.
Acrocanthosaurus' arms were not large enough for it to use them to bring down prey, as with all large theropods, it used its jaw.
@@fredlueplaystudios2325 "lion claws aren't large enough to bring down prey, like all carnivora it uses it's jaws".
Like with modern bird of prey, Arco used it's claws in conjunction with its mandible to take down prey.
Arco didn't have 6 unch serrated claws with large powerful arms to play rock paper scissors 🤣🤣
@@trvth1s T. rex's arms were also powerful and strong, so they also used their arms to bring down their prey, didn't they?
@@fredlueplaystudios2325 trex arms and claws were significantly smaller than Arco. As I mentioned in my original comment, I saw a reconstruction of both animals next to each other in the museum if natural history located in Dallas Texas
@@trvth1s Looking at paleoarts, the arms of both are pretty much the same size and just because you've seen reconstructions of them doesn't mean they're necessarily right.
The acro is my favourite dinosaur. I am absolutely awestruck by the artworks in this video
Acro is my favorite dinosaur! Thank you for making this video. It’s nice to see the Acrocanthosaurus get some love. ❤😃
so if Walmart started selling acro eggs you'd buy one? siiick!
When asking how T-rex and Acro would have interacted, it would be Adult T-rex killing/chasing off Acro, Adult Acro killing off subadult and smaller T-rex, and/or complete avoidance of each other. That's how modern carnivores interact with each other now.
Pretty much. Unless a predator finds itself in a desperate situation or some instance of low risk (a young or injured predator) there is no advantage to fighting other predators were there is a high probability that even the victor will be injured.
And depending on their ecological niche, they would have no reason to fight since predators that hunt different types of prey don't end up in conflict, only in extreme cases.
Acro would definitely be some serious competition for the rex and vise versa seeing how they're roughly the same size
@@alexthomas6274Trex is 9-10 tons and the acro is 6. How are they around the same size? Lmao. So many uneducated people flapping their gums
@@Boss-ot1iy Acro is 7 tons and 38 feet long. The biggest Rex Scott was 40 feet and only 9 tons Rex is slightly bigger.
7:43 I like how the Acro head you show when talking about its demise looks so sad.
My first exposure to this dinosaur was Jurassic Park Operation Genesis. I've always had an appreciation for it since.
Great narration on the pre-historic dinosaurs. I like the Acrocanthosaurus best between it and T-Rex. It was a more vicious looking predator dinosaur. Also graphics on this video are terrific.
You know, I'm glad clips of Monsters Resurrected are shown. Sure, it isn't the most accurate documentary, but I have a soft spot for it. It introduced me to not only Acrocanthosaurus, but also Paralatitan, Carcharodontosaurus, Rugops, Amphicyon, Megalania, Procoptodon, Diprotodon, and Thylacoleo
Acro is a Charcharodontosaurid which were usually found in southern hemisphere (Africa & S.America) so the fact this one was in North America is very peculiar. S.America was not attached to N.America in the Cretaceous, so then how did Acro reach N.America? Did it island hop maybe?
It could’ve been endemic. After all, North America had allosauroids, and there’s a theory that saurophaganax is an early branching charcharodontosaur
Maybe acro, and the other multiple unnamed North American charcharodontosaurids are descendants of saurophaganax?
@@PaleoBasil oldest carcharadontosaurid is older than saurophaganax
Earlier Acro's may have swam to North America before it drifted to far prior to Pangeas splitting or they had been their before and had no reason to swim out until other land became too distant maybe?
Carcharodontosauridae the most successful group of all carnivores . The group has some of the largest land predators of time. Many are almost as large or even larger than T Rex.
Giganotosaurus, Carcharodontosaurus, Tyrannotitan, Mapusaurus, Sauroniops, Siats, Acrocanthosaurus etc all are huge carnivores in same group
uber?
im glad people are still making dino content, i havent seen much in recent years
Dinosaurs popularities are dying day by day
@@zebgiganotosaurusgaming tbh this may not be that bad.
While I think paleontology and dinosaurs should be popular, I don't think it's too good if dinosaurs are mainstream.
We live in a time where many people believe that Velociraptor was a large, featherless lizard on steroids with human level intelligence, that Spinosaurus was the most powerful being ever and that large theropods only knew how to kill and roar constantly.
Some people working at museums have even reported some children asking where they can see the Indominus (apparently they didn't even pay attention to the movie).
This is what happens when dinosaurs get mainstream popularity.
They get portrayed as monsters.
And now we have a lot of "dinosaur experts" that can't accept that their favorite dinosaur was just a normal animal and not an evil killing machine that constantly fought with other large dinosaurs.
yeah, who does dinos anymore? they're so yesterday.
Make no mistake, the Acro doesn't get enough attention imo, but it does get quite abit of spotlight time. I feel like the Acro is that "one really kinda cool dino alot of people know about even if its not full celebrity"
Ngl Acro is my favourite large carnivore dinosaur and I feel like it really doesn’t get much recognition in media but like you said has some popularity not much but some
@@kyachdistent1301 yea I like how you put that in to detail about how people can’t name any other dinosaur besides T-Rex and maybe spino so yea it’s true
@@WastelandarchitectTorvosaurus is also very underrated!
I think the most likely purpose for the neural spines were for a hump. this way the added muscle would help with bite and help with stress that could have been caused by bitting, Or (my own theory) to pick up certain prey and throw them short distances. This would allow them to use its claws while the prey is down
Well another theory for Acro’s taller neural spines was that it was where powerful muscles were attached to support and strengthen the neck and jaws. Think less like the hump of a camel more like the “hump” of a bison. It’d be pure muscle, making these already powerful predators even stronger then they already are.
@@jalenjordan7219 exactly what I was thinking
@@jalenjordan7219 imagine t Rex with a hump
@@kyachdistent1301i think the hump looks cooler. reminds me of a bison
As a Texas resident I’ve seen an acro on display in San Antonio’s Witte museum and the tracks in Glen Rose. I’ve gotta say it’s a rather unique and menacing looking theropod.
Ray Romano is badass at Dino documentaries
The acro is by far my favorite therapod, it's kinda underrated compared to T Rex
@@kyachdistent1301 facts
Hunting larger sauropods is just what the Allosaurid lineage did, and without DNA evidence you're never going to convince me that carcarodontids were not descendant from Allosaurids, as they look and seemed to have acted like Allosaurus, only much larger.
Uhh Charcarodontosaurids are Allosaurines?
Thank you for this video!! You never disappoint!!
Where I first heard of Acros was from one of my favorite childhood novels Raptor Red. They were portrayed as dangerous competitors to Utahraptors.
Yes, same!
In terms of interactions between Acro and Rex.
They’d probably largely avoid each other for the most part, with Rex going for ceratopsians and hadrosaurs, while Acro would go for titanosaurs and ankylosaurs.
The only times they’d ever interact would probably be territorial disputes, and even then it’d probably wouldn’t get too violent, with the two animals intimidating each other until one backs down.
I like to think Carnivorous Dinosaurs hunted Prey similar to Today's Modern Animals like Lions & Wild Dogs. As for the Large Carnivorous Dinosaurs, They probably killed their prey Ruthlessly due to their Large Size.
Just sub’ed. The short format (< 10min) shows drew me in. Thank you. 🥇🏆
Hot take, T-Rex is the most popular because its the only one that people can say without sounding like theyre having a stroke.
It's probably most popular because:
- it's one of the largest theropods, and land predator of all time
- it has some of the most complete fossils of all dinosaurs
- it has quite a lot of fossils compared to other dinosaurs
- it was discovered and properly described much earlier than many other dinosaurs
- it gets included in like every dinosaur media
But tbh, you have a point.
Not only does the name sound cool, but it is also very easy to pronounce.
And it also shorter version of it's name (T rex) which most dinosaurs don't have.
Usually dinosaurs with easier to pronounce and "cooler" names are the ones who are more popular than similar dinosaurs:
Stegosaurus > Tuojiangosaurus
Tyrannosaurus > Acrocanthosaurus
Spinosaurus > Oxalaia
Velociraptor > Deinonychus (tbh I think Deinonychus sounds cooler but most people seem to disagree)
Argentinosaurus > Dreadnoughtus
@DeletionByFive ok Baryonyx does kinda work
Okay but people can say Velociraptor and Dilophosaurus just fine.
This is my favorite Carcharodontosaurid, but T. rex will always be my favorite.
Woah, did not expect my Artwork to feature in this. Great Video by the way
I guess being a nightmare to sauropods runs in the family
Acrocanthosaurus are nothing to a giant healthy adult sauropod
Literally.
@@mhdfrb9971 was there anything that ever was?
@@marweha7002 No, nothing that we know of but Mapusaurus and other large carcharodontosaurids may have bitten chunks off of them and that may have caused them to die of infectious wounds later on.
It would actually be a nightmare for Acro to have an adult sauropod heading towards him, it sure is creepy.
*Me to the thumbnail* “um hi?
The “Terror of the South” exhibit in the Raleigh Museum of Science is an acrocanthosaur. They were all over the southern US.

crazy to think that these animals once existed on this planet long ago. Like damn, nature made this bro.

@tossupeaterWhich is why, i already said. T-rex is the answer of what Nature has been offering. Nature offered Armored and Horned herbivore? There's a predator that's going to be created by nature itself to answer that challenge.
This is textbook example of survival of the fittest. Not to be taken as offence.
Great video! I love the Acro it’s one of my favorites.
Acrocanthrosaurus is a Cool Dinosaur!!! 😎👍

Acrocanthosaurus is one of my favorite large theropods, up there with creatures like Gorgosaurus and Torvosaurus. I really hope it gets some more representation in media (hopefully not the jurassic world franchise though).

i think you also had siats? which was as long as acro but probably not as tall or heavy. acro is routinely underrated i totally agree, because it just looks like a dense, compact, bearish grappler like t rex, with large teeth and a strong bite, akin to earlier torvosaurus
Acros are the main antagonist is the novel Raptor Red. One meets its bloody demise in the maw of a Mosasaur.
I love that book!
It’s one of the reasons why Acro is my favourite dinosaur
No one ever depicts the t-Rex and those like him eating the dead giant dinos like a pack of vultures. I imagine they did this often.
The idea that T-Rex and other theropods being pure scavengers is completely ridiculous and has been rebuked,
But theropods and t-Rex wouldn’t pass an easy meal, they would 100% like modern day animals eat a dead carcass from a dead dinosaur,
They would both hunt and scavenge for survival in there environment

Acrocanthosaurus is my One of, If not My Favorite Carcharodontosaurid. Only Rivaling that of Giganotosaurus
The 2 theropod would probably end up avoiding each other if given chance.
The tracks in Glenn Rose do in fact show a sauropod being hunted. The actual tracks that show this are in a museum in New York. You can actually see the carnivore missing a few steps indicating that it was most likely leaping onto the side of a sauropod. That's the "overlap" mentioned before.
Can You Make A Video About Brygmophyseter Shigensis?
I've been to the Glenn Rose park, great place to go and walk around at.
I hate how Monsters Resurrected did the Acro dirty.
Finally, someone pronounces my name correctly.
Wow, nevertheless I wish I could have lived when they lived,,it would have been very interesting
Lets just say that it would be a bad idea to time travel into the pinaccle time of dinosaurs (The Creteceous Period) You would hear low frequency-type sounds from giant theropods that would make your whole bosy vibrate. And a smaller dino Like Deinonychus would just kill you casually. AND remember That Tyrannosaurus can run 44 Kmph. Terrifying Enough?
Great video!
I always confuse Acrocanthosaurus and Characadontosaurus, not know they're actually related
Glenrose Texas is a pretty cool visit. They also have cheap cabins you can get instead of a hotel.
Watching them reminds me of Jurassic park game, since the first theropod avaible was them.
Acrocanthosaurus is such an underrated Apex

Acrocanthosaurus is 3rd largest theropod from North America after T Rex & Sauropahaganax. It's possible that Siat meekerorum could be bigger than Acrocanthosaurus since the holotype isn't fully grown

But it could’ve been a different name
good ol freight trains from hell
First off, congratulations on 100k views in 3 days.
Secondly, what we dont consider is that humans have kinda trashed the world. Before humans, there were plenty of “rare” creatures. Thus, dinosaurs were not like animals today (elusive) but rather they would be absolutely everywhere. Imagine that
Dinosaurs where gone 60 million years before humans showed up, it's not our fault these creatures are not around today.
@@richardthompson6366 they still technically are since birds are dinosaurs.
But yes, when it comes to non avian dinosaurs we didn't do anything to make them extinct.
But we are still good at making many avian dinosaurs/birds extinct.
My thoughts on the acro' predatory ecology is this I think the arms may have been more important for predation when the creature is younger. A regular avain grabbing and pulling with the head will draw tissue over the recurved and serrated teeth cause devistating cuts to muscle and bone like a shark or kommodo dragon bite. I think hunting adult sauropods, particularly the isolated sick and injured in favorable terrrain or at night would have been done. And I think that thise jaws and teeth could effectively immbolise even large animals by damage to muscle anf ligiments.
Such an underated dinosaur.
Ngl this is my number 1 fav dinosaur second is spino and third was aerosteon
nice
awesome animal tbh
5:00 jesus that's a horrifying thought. Imagine a pack of 3 or 4 of these behemoths chasing you threw the under brush surrounding you. Yikes
They would only do that if severely starved
One of my favorite dinosaurs
We need genetically engineer these creatures back into existence.
i feel like hunting by bleeding larger prey is an interesting method, that they bit chunks out of larger animals over longer distances and basically "live fed" themselves off of prey, until the animal bled out
Warpath Jurassic Park brought me here.
Hot take: I am not the biggest fan of Julian Johnson-Mortimers animations. The models are nice, sometimes a little too much on the Jurassic Park side, and he really hits the nail on the head when it comes to putting the animals into the real footage environment, just look at the scene at 0:15, the lighting is spot on. However, the movement is terrible most of the time, especially with the carnivores. They look super cumbersome, like they can hardly run, and waddle from side to side, while it's actually suggested that theropods would place their feet in front of each other right under their body.
I think of the bison when i see neural spines that are tall but not crazy like Spinosaurus. I think it was probably just a bump and all those muscle attachments allowed it to really control the movement of prey with it's big mouth
My Favorite!
These things are basically 5 ton Road-Runners! I've seen what the tiny modern ones do. Sod that!
(Anyone who wants to see raptors pack hunting just check out Harris Hawks in action, plenty of vids to choose from)
That shot of it wrestling with an anky is odd, since their teeth were blade-like and designed for flesh slicing. Grabbing an anky head like that would break multiple teeth.
Dinosaurs are Super Cool!!! 😎👍
Man still ruled over them as the apex predators we are.
You should talk about Gargantuavis
What’s to say it fed on carrion too.
Any indication that their legs could be used for jumping? I see that spine and immediately think about drag reduction.
Btw there is some theory's that acro met sith siats and utahraptor
