*Allosaurus* is a large carnivorous theropod that lived in North America and Europe during the Jurassic. *Allosaurus* will consist of three species in Prehistoric Kingdom, *A. europaeus*, *A. fragilis*, and A*. maximus (also known as Saurophaganax maximus)*.

It is yet to be added to Prehistoric Kingdom.

## In-Game

### Description

*Allosaurus* is the poster-boy medium theropod, known for its large head, developed arms, and a mouth full of dozens of serrated teeth. It is also recognized for its distinct pair of horns above the eyes, an extension of the lacrimal bone which are in the front of the eyes, a trait which varies among the various species of *Allosaurus*. In-game, all three skins correspond to a different species of *Allosaurus* with *A. fragilis* being the default due to its established presence in popular culture as well as the fact that it is the type species of the genus *Allosaurus*.

The closely related *Saurophaganax* was also present in the Morrison Formation and lived at around the same time and place as *Allosaurus,* though *Saurophaganax* was much larger than and more robust.

Compared to the others, *A. europaeus* is the smallest and was found in Portugal rather than North America. Growing up to 8 metres in length, *A. europaeus* was still an intimidating animal. Unlike its relatives, *A. europaeus* also developed far more boxy crests compared to the pointed and rugged ridges of *A. fragilis.*

## Paleontology

*A. fragilis* lived alongside other famous dinosaur species from the Morrison Formation, such as *Dryosaurus*, *Stegosaurus*, *Ceratosaurus,* *Torvosaurus*, *Camarasaurus*, *Diplodocus* and *Brachiosaurus*. *A. europaeus* was contemporaneous with *Miragaia*, *Lusotitan*, *Dinheirosaurus*, *Lourinhanosaurus,* and the European *Torvosaurus* species *T. gurneyi*. There is evidence for cannibalism amongst Allosaurs, such as shed teeth amongst rig fragments, possible tooth marks on a shoulder blade, and cannibalized skeletons among the bones at various lair sites. It is speculated that *Allosaurus* was a pack hunter due to the large accumulation of *Allosaurus* remains at the same sites, comparable to mass death assemblages of more recent pack hunters such as Dire Wolves in the La Brea Tar Pits.

Although in-game *Allosaurus* contains the species *A. maximus*, it is now thought that *Saurophaganax* was its own distinct genus based on the new view of basal tetanuran theropods, and some new *Saurophaganax* material from New Mexico may help clear up the status of this genus. However, there is still a third species of *Allosaurus* which was described in 2020, called *A. jimmadseni*, that was named after James H. Madsen Jr. who was the first state paleontologist in Utah. Unlike *A. fragilis*, *A. jimmadseni* had thin, blade-like crests that ran over its snout and reached its highest point over the eyes. Being discovered from the Lower Morrison Formation, *A. jimmadseni* is geologically the oldest species of *Allosaurus*.

It is commonly said that *Allosaurus*'*s* jaws were analogous to the blade of a hatchet due to its large gape and strong neck muscles, however even with its wide gape a hatchet style bite would not be able to make proper contact with the prey animal in a vast majority of instances with the lower jaw getting in the way. It is far more likely to have been biting and tearing in a normal theropod fashion while using its robust forearms and strong neck muscles to help subdue large struggling prey. This view is backed up by injuries to the tendons of the arm sustained by *Allosaurus.*

*Allosaurus* was found in 1877 by Othniel Charles Marsh and its name means "different lizard".

## Trivia

* Allosaurus was one of the dinosaurs available in the 2017 Prehistoric Kingdom demo.
* Initially Allosaurus was going to have two feathered skins but they were cut, this skins were present in the 2017 demo.
* Allosaurus is one of the many animals in Prehistoric Kingdom that has alternate species for it's skins.
* Allosaurus maximus, the species of the badlands skin, is considered by some paleontologists to be a separate genus called Saurophaganax.
* Allosaurus is one of the most popular Theropods, appearing in multiple pieces of media, such as the *Jurassic Park* franchise, prominently featuring in *Battle at Big Rock*, and the critically acclaimed *Walking With Dinosaurs*. It’s level of fame is only next to Tyrannosaurus.
