Acrocanthosaurus was a large theropod dinosaur which lived during the Aptian and early Albian stages of the Cretaceous period. Like most dinosaur genera, Acrocanthosaurus contains only one species; A. atokensis.

In Real Life

Acrocanthosaurus was around 11.5 meters in length, and weighed around 6.2 tonnes (6.8 tons). Acrocanthosaurus was likely the apex predator of its habitat, preying on animals such as Tenontosaurus and juvenile Sauropoesidon.

Acrocanthosaurus' arms were not very mobile, suggesting that the head was the animal's primary weapon. Acrocanthosaurus likely wasn't particularly fast, based on the proportions of the animal's rear legs.

In The Isle

Acrocanthosaurus is a playable dinosaur. It is smaller than a Tyrannosaurus but bigger than a Allosaurus. Acrocanthosaurus is also part of the Bleeder Branch, a branch of carnivores the specialize in massive bleed. While alone, you must only hunt small to medium sized prey that have very few defences but when in a pack, you can hunt prey that are dangerous like Triceratops, Stegosaurus, and, if the pack is large enough, Shantungosaurus. The only prey items you cant really hunt are Ankylosaurus and Puertasaurus as the Ankylosaurus can do huge damage to you and break your leg and the Puertasaurus is difficult to be killed by any carnivore and will kill you very quickly with one stomp. Also Its should hide away from bigger Predators like Tyrannosaurus,Giganotosaurus and Spinosaurus.

Behind The Scenes

Carcharodontosaurus and Giganotosaurus were originally going to be alternate skins for the Acrocanthosaurus. Ultimately, however, Giganotosaurus instead became it's own thing, with Carcharodontosaurus being an alternate skin for it instead.
