Acro, tyrannotitan, charchar, maraxes, mapu, and the gigantic giganotosaurus This whole family was made of elite predators. It’s bonkers when you think about it
As an ACRO ENJOYER all things said in this video are true. He should be more in the spot like like rex, spino and giga because he is also just as large.
It really brings Joy to my heart to see Acrocanthosaurs get more attention! Learned about the species a while ago from some dinosaur trading cards but Only relatively recently did it become my favorite! I would've initially imagined the spines were for mating display or hear regulation like a dimetrotodn but I find the possibility of extra connective muscle very likely when compared to bison spines too hmmm.
I live close to Dinosaur Valley State Park in Texas. If anyone isn’t familiar, this park is famous for having two sets of footprints along a creek bed and just a few days ago, during the awful droughts here, even more tracks have been found. It’s believed the therapod prints likely belonged to Acrocanthosaurus, so I’ve always had a super special place in my heart for this Dino. So very cool.
I have to say, I've always had the impression that Acrocanthosaurus was comparable in size to it's other cousins like Mapusaurus, Tyrannotitan, Carcharodontosaurus, Giganotosaurus, etc. However recently, I've realized that it's noticeably smaller than it's fellow carcharodontosaurids (I say that, but a 5-6 tonne predator is still a huge animal). Regardless, it's still a very neat dinosaur.
I really want to see a case study of Barinasuchus even if these little known about it and the environment it inhabited. all I could say that it was most likely a genius of large Sebecid that lived from the Eocene to Miocene but with how few fossils we have right now it's hard to say. as for creatures it lived alongside, we'll all I could find from the same formations it was found in where the Notoungulate Miocochilius and the litoptern Theosodon. what I can say for sure is that we need many more fossil explorations to South America in order to uncover the mysteries surrounding this fascinating Crocodylomorph.
@@TheOverseerDebates I absolutely did, it's fantastic and not alot of people talk about it, so it's nice to see a video about this animal with some work put behind it!
I think there was A Documentary Megabeast that had showed they would Latch onto the Enormous Sauropods based upon track evidence. Do you think you can do A video of Acrocanthosaurus vs Tyranosurus Rex. I also personally think that as a predator it is most likely Acrocanthosaurus had a back like mentioned with the Bison theory therefore adding to the Robustness of this magnificent species. I figured it would be a good Match up for T.rex since A 2009 study showed they where quite comparable in size.
The eastern Appalachia part of mesozoic North America was a reducing environment, a severe Lack of fossilization going on so it's frustrating to determine what was going on, I suspect the inland sea had something to do with Acro being stuck where it was.
Appalachian dinosaurs do need more love, and Acro seems to have crossed into Appalachia during periods when the sea didn't completely isolate Appalachia and Laramidia from one another.
Lets see, had strong arms, decent but limited ranged but thick gripping claws, has a biteforce nearly twice the spino’s bite, is fast, and hunts sauropods. This man is the balance in trhe theropod family☠️
Acro is definitely in my top favorites forsure...tied with Yutyrannus, the REAL Deinonychus, Saurophaganax and, with more discoveries and knowledge...my personal favorite...Thanatotheristes...The Reaper of Death
The entire “bite prey and then just do nothing but wait for it to weaken and die” thing is almost certainly false, and is based entirely on FALSE ideas about how living analogues like Komodo dragons hunt. In reality they try to bleed out their prey ON THE SPOT (which is how Komodo dragons ACTUALLY hunt), and the same likely applies to all of the carcharodontosaurs. Fun fact: Acrocanthosaurus pulled the “completely fill the medium-sized predator niche using juveniles” thing even more extensively than tyrannosaurs did.
awesome work, as i also think the Acrocanthasaurus is awesome. Unrelated, but has anyone ever made a vid about why carnivore dinosaurs have shorter arms compared to their legs? I find it odd that even those with "longer" arms, like Spinosaurus, nevertheless seems shorter than the rest of the body.
The problem with that Giga estimation (which I assume is Dan Folkes) is that it’s based on a fragmentary jaw. Given how much the size of theropods heads can vary from individual to individual means it can’t accurately be said to even be any bigger than the holotype. If that specimen is going to be used, then used the fragmentary fossil of “Cope,” the Tyrannosaur with a much thicker femur than Scotty. Otherwise, the holotype of Giga is the more accurate specimen and I don’t believe that specimen even tops 9 tonnes iirc.
@@festyfestivathen you should use a more average specimen of t rex in comparison to giganotosaurus if your going to discount the paratype and just use the holotype.
@Why79-dx4rf Why? This list is obviously using the largest specimens and if you’re going to use the jaw fragment, may as well use the odd fragmental rex specimens that indicate individuals larger than Scotty.
@@festyfestiva well I'm just saying, if one is to compare giganotosaurus to t rex, and exclude the paratype then they should use a more average sized t rex so as to make a more accurate comparison on the species level.
I find it odd that, in the list of what it's neural spines might have been used for, no-one has suggested that they might be a base for a fat storing hump. Yet, when you look at modern mammal skeletons, the one whose back resembles that of Acrocanthosaurus most is a dromedary camel. One of our biggest issues is that we have no living animal that has massively tall neural spines such as is found in spinosaurs and the synapsid animals dimetrodon and edaphasaurus. Sometimes, skeletons of modern animals can give insight into what functions these skeletal features may have performed, which brings me to a second point. The skeleton of concavenator has tall neural spines over the hip, a small peak that, but for it's placement, looks a lot like that of a modern bison. Now, we know that the spines in the bison are used for neck muscle attachments, to move and control its' massive head. Perhaps the neural spines in the concavenator fulfilled a similar role, providing muscle attachments to back and legs of the beast. I'm not sure why they would have such an arrangement, but it is an intriguing thought...
No point in a land based carnivore storing fat in a hump which would hamper its hunting ability. Some carnivore mammals store fat only because of hibernation. There is not a single lizard on earth now that stores fat in any way.
I'm writing a novel about dinosaurs and you know what, Acro is the villain in my book There were so many dinosaurs I wanted to use as a villain like Carcharadontosaurus or Allosaurus but I chose Acrocantosaurus This beast is criminally underrated and I think I should show it some attention it deserves But well it's not my only villain I'm planning for human antagonists too and scenes of scientifically accurate dinosaurs killing humans in brutal and gory ways
That is why there were areas where their species diversity was growing? If the slow extinction hypothesis were true, then the species diversity of dinosaurs would be declining across the planet, not locally.
After researching Komodo Dragon hunting behaviors it became apparent to me that a similar strategy our lizard bros employ against Water Buffalo could also extend to these large Theropods. Having a septic or venomous bite, a decent sized group, & decent stamina would allow these apexes to take on gigantic Sauropods that were isolated from their herd. Literal anklebiting over days or weeks could take down some of the most massive animals ever to exist; a more believable feat when you consider their dentition & jaws are made for slashing, not crushing like a Tyrannosaur.
