Compared to other powerhouse predators on Isla Sorna, Acrocanthosaurus fits the bill as a powerhouse in it's own carnivorous way. Hunting prey as large as itself, this astonishing carnosaur establishes itself well among the heavy hitters of the food chain. It's serrated teeth and impressive strength make it a prominent predator of ornithopods, ceratopsians and sauropods.


Acrocanthosaurs are frequent residents in wide spread Northern environments such as plains, grasslands and floodplains, often living in the forests that are close to these areas. In fact, some have even been found sharing large sympatric territories with Allosaurus in these locations.


Acrocanthosaurus is seen by many observers to be incredibly unpredictable. In most cases they are extremely aggressive, showing no fear in the presence of predators who rival them in size and power. In the mating season, males and females form monogamous pairs and stay together for life, raising their young equally. Rogue males are easy to identify by their high levels of aggression, going so far as to even kill without provocation.

Regarding their sympatry with Allosaurus, the two theropods seem to show respect for one another and often avoid competition through communal feeding, primarily when feasting on sauropods. 

Though they are not classified as man-eaters, Acrocanthosaurs will still attack and kill but will not devour any human hunters or poachers that intrude on their territories.


As a large carnivore, Acrocanthosaurus prefers hunting medium to large prey, using it's razor sharp teeth to tear into it's victims. Such potential prey includes mainly ornithopods such as Tenontosaurus, Edmontosaurus, Parasaurolophus, Iguanodon, Corythosaurus, Lambeosaurus, Hypacrosaurus, Gryposaurus, Maiasaura, Saurolophus, Camptosaurus, Ouranosaurus, Shantungosaurus and Brachylophosaurus. As stated before, Acrocanthosaurus is also a prominent predator of sauropods. Indeed, mobs of this carnivore have been spotted stalking after herds of Diplodocus, Camarasaurus, Apatosaurus, Mamenchisaurus, Amargasaurus, Saltasaurus, Argentinosaurus, Paralititan, Sauroposeidon and Dicraeosaurus, aiming for young individuals. Ceratopsians make up at least 20% of the Acrocanthosaurus diet, with Triceratops,Torosaurus and Pentaceratops being the most preferred targets.

At the juvenile stage, Acrocanthosaurus hunts Dryosaurus, Montanoceratops, Pachycephalosaurus, Fukuisaurus, Thescelosaurus and Ornithomimus.

Interspecific Competition

Acrocanthosaurus is more commonly able to intimidate smaller predators at carcasses. Ceratosaurs, raptors and even small abelisaurs give it a wide berth. It's natural enemy, Deinonychus, instinctively avoids hunting grounds that are occupied by Acrocanthosaurs.

In sharp contrast, Acrocanthosaurus competes more fiercely against the bigger predators. Though Tyrannosaurus is seen as a vicious rival, the greatest enemies of Acrocanthosaurus are Torvosaurus, Saurophaganax, Fasolasuchus and Carcharodontosaurus. Each of these predators poses a threat to both adults and juveniles when it comes to confrontations over prey.

The one and only Acrocanthosaurus, the theropod who ruled North America in the Cretaceous long before Tyrannosaurs took over years later.

I first learned about this dinosaur when I played Warpath: Jurassic Park. It was the first dinosaur that I used in the game, those were some good times. Afterwards, I began studying this carnivore all the way to my adult years.

But anyway, the next theropod to get a profile will be the raptor known as Deinonychus, who actually coexisted with this giant predator.

In "Jurassic Park: Operation Genesis", Acrocanthosaurus and Carcharodontosaurus are the only two big carnivores who won't try to kill each other (presumably because they're both from the same family).

I know, but that's just how they were programmed in the game. In reality, most predators still compete fiercely even if they are related. Today's predators such as Lions and Leopards are in the same family, but they don't get along, neither do Tigers and Leopards. 

If these two theropods were to actually meet each other in real life, they would have been very aggressive with one another.
