Allosaurus europeaus is a smaller species of Allosaurus known from the Lourinhã Formation in what is now Portugal.
Allosaurus is a large carnivorous theropod that lived in North America and Europe during the Late Jurassic. It will consist of 3 species in Prehistoric Kingdom: A. europaeus, A. fragilis and A. jimmadseni. It is also the base genus for Saurophaganax.
It is confirmed to be coming in Update 17.

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 crests above the eyes, a trait which varies among the various species. In-game, all 3 skins correspond to a different species of Allosaurus.
- Allosaurus fragilis is the most plain of the 3 Allosaurus species, with a subdued brown spotting with brighter orange crests which are more sharply pointed than the other species. A. fragilis also has teardrop markings underneath its eyes not unlike those seen in big cats such as Panthera, used to cut down on glare while hunting.
- Allosaurus jimmadseni bears complex stripes and splotches on a green background with striking yellow-orange rounded crests. It is the largest on average of the Allosaurus species in-game, and also has a much smoother "cheekbone" region than the other Allosaurus species, as seen in the fossil remains of these animals.
- Allosaurus europaeus is the smallest and was found in Portugal rather than North America. Unlike its relatives, A. europaeus has far more boxy crests with enhanced nasal crests compared to the pointed and rounded ridges of A. fragilis and A. jimmadseni. A. europaeus also is the only species of Allosaurus in-game to poses sexual dimorphism, with the males of this species bearing striking blue highlights on its crests and body not dissimilar to those of peacocks.

Allosaurus fragilis, the "Fragile Different Lizard", was named in 1877 by Othniel Charles Marsh from a scrappy set of remains including parts of some vertebrae, a rib fragment, a toe bone and a tooth. Its genus name referred to the morphology of its vertebrae which at the time was unique among known theropods, and the species epithet was in reference to the weight saving adaptations in its bones. This, however, was not the first name assigned to this animal, in fact the animal that would become Allosaurus went by a number of monikers. At first, Allosaurus remains were assigned to the European theropod Poekilopleuron, before being given its own genus "Antrodemus". If prevailing usage went towards "Antrodemus", it is quite possible that it would have remained in use to this day, however eventually concerns about the location data and undiagnostic nature of the "Antrodemus" type specimen raised by James H. Madsen Jr. during his study of the Cleveland-Lloyd Dinosaur Quarry eventually led to Allosaurus taking precedence over this older name after decades of "Antrodemus" being used. Other names that were given to specimens now considered to belong to Allosaurus include "Creosaurus" and "Labrosaurus" named by E. D. Cope, and "Epanterias" also named by Marsh.
A second species of Allosaurus in the Morrison, A. jimmadseni, was described in 2020 and named after James H. Madsen Jr., who was the first state paleontologist in Utah and did foundational work on this theropod through his monograph on the Cleveland-Lloyd remains. Unlike A. fragilis, A. jimmadseni had thin, blade-like crests that ran over its snout and reached its highest point over the eyes, and a much more shallow jugal bone in the animal's jaw. Being discovered from the Lower Morrison Formation, A. jimmadseni is geologically the oldest species of Allosaurus.

Paleoecology[]
Allosaurus was a top-order carnivore in both North America and Europe, and likely had a great effect on the ecosystems it dwelled in as a powerful and dynamic predator. A. fragilis and A. jimmadseni lived alongside other famous dinosaur species from the Morrison Formation, such as Dryosaurus, Stegosaurus, Ceratosaurus, Torvosaurus, Apatosaurus, Brontosaurus, Camarasaurus, Diplodocus and Brachiosaurus. A. europaeus was contemporaneous with Miragaia, Lusotitan, Dinheirosaurus, Lourinhanosaurus and the European Torvosaurus species T. gurneyi. Allosaurus seems to have had a varied generalist diet as evidenced by numerous bite marks on sauropods and Stegosaurus plates, and injuries consistent with strikes from the thagomizers of Stegosaurus. These theropods are widely known to have numerous other grievous pathologies, with famous individuals such as "Big Al" sporting suites of life-altering injuries. Some have used this abundance of injuries to suggest it was an abnormally aggressive theropod, however any such interpretations are speculative, unable to be tested with current available data, and may just be a due to the fact that we just have more Allosaurus individuals than other large theropods. In fact, similarly severe injuries have been noted in other theropods such as Dilophosaurus and Gorgosaurus. There is also evidence for cannibalism among Allosaurus, such as shed teeth amongst rib fragments, possible tooth marks on a shoulder blade and cannibalized skeletons among the bones at various lair sites.
It has been 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. However, doubts of the Cleveland Loid Dinosaur Quarry representing a predator trap have been raised due to peculiarities at the site. Cooperative hunting may have been useful in hunting large sauropods, however confirmation of this strategy being used in Allosaurus has yet to be discovered. Some have suggested that Allosaurus didn't even hunt at all and was primarily a scavenging animal living off of sauropod carcasses, however while Allosaurus likely would have certainly scavenged when it could, numerous instances of active hunting behavior are known from Allosaurus. This includes mired sauropods at the remarkable Howe Dinosaur Quarry which are preserved with limb bones still standing sunk in ancient mud, surrounded by the rest of their remains and numerous Allosaurus teeth strewn across the site.
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, a method that has been compared to the hunting methods of saber-toothed cats such as Smilodon by paleontologist Dr. Robert T. Bakker. Despite lacking the distinctive saber-teeth of the felids, both Allosaurus and Smilodon have reduced bite forces, increased jaw gape, powerful neck musculature, and powerful arms used to grapple prey. This view is backed up by injuries to the tendons of the arm sustained by Allosaurus, showcasing their use in strenuous activities. Once prey has been subdued, their powerful neck muscles would have been used in concert with their feet to tear out chunks of flesh in a similar manner to a modern falcon, as evidenced by the construction of its neck being conducive to vertical motions and minute stress fractures on their foot bones. These analyses have also suggested that Allosaurus was capable of moving its head and neck relatively rapidly and with precision, a trait which would be useful when attempting to strike at prey or rivals with lower risk.
