Acrocanthosaurus | The King of Early Cretaceous North America

[@nono9543]

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.

[@planetdee3587]

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.

[@blakewinter1657]

[@seanfletter9098]

Acro rolls off pretty good and is awesome in the game The Isle.

[@PyroBlonde7777]

@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.

[@planetdee3587]

@@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.

[@calessel3139]

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.

[@amberanime]

@@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.

[@Valoelify]

@@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.

[@windowsVD]

@@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.

[@tomcross3000]

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.

[@rileyernst9086]

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.

[@rileyernst9086]

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.

[@rileyernst9086]

But yes stokesosaurus, a small tyrannosaurid. Was found in the morrison.

[@islamicschoolofmemestudies]

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.

[@rileyernst9086]

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 !

[@trvth1s]

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.

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

[@jalenjordan7219]

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.

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).

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.

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).

[@lndominusrex6102]

Torvosaurus is 11.4m & 5.7 tonnes Acrocanthosaurus is 11.5m & 5.8 tonnes Gorgosaurus is 9.3m & 3.3 tonnes

[@kade-qt1zu]

@@lndominusrex6102 Well, those are some very interesting facts. May I ask what species of Torvosaurus those estimates are for?

[@lndominusrex6102]

@@kade-qt1zu Edmarka Rex or Torvosaurus tanneri is that size. Torvosaurus gurneyi is 10.8m & 4.8 tons

was this called something else at one time? i never heard of this beast

[@Simple_Leopard2A6.enjoyer]

I think it was always called Acrocathosaurus from the start, But it could’ve been a different name

[@spinosaurusaegyptiacus49]

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

[@Taurovenator783]

Imagine how big Siats would be when he was an adult

[@StanFalade]

Before Saurophaganax and tyrannosaurus*

[@ArealightsFactory]

nice

[@weirdkidwithacrystalball1322]

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

[@rileyernst9086]

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.

[@ThePanzerKorps]

Acro is my favorite because of Primal Carnage: Extinction.

[@Wastelandarchitect]

Ah yes primal, carnage extinction brings joy into the eyes

[@yibinkang4498]

Fav dino featured in dbwc

[@maxdaly8185]

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.

[@Simple_Leopard2A6.enjoyer]

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

Any indication that their legs could be used for jumping? I see that spine and immediately think about drag reduction.

[@funwithfish1507]

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

[@richardthompson6366]

Dinosaurs where gone 60 million years before humans showed up, it's not our fault these creatures are not around today.

[@obambagaming1467]

@@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.

[@MbisonBalrog]

We need genetically engineer these creatures back into existence.

[@GREYFLWRMUSIC]

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.

Where is this Acro footage from? Is it a new dino documentary? If so, what is the name?

[@thedellyrulez]

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

[@tallman2210]

I've seen the skeleton in the Raleigh museum.

[@timetraveler1973]

merry christmas. i have traveled in the past and future. acro is pretty cool. almost as cool as t-rex. but lighter and weaker and faster.
