***Allosaurus*** is a genus of carnosaurian dinosaur in the *Jurassic World Evolution* series. One of the most famous theropods, *Allosaurus* originated from Late Jurassic North America.

*Allosaurus* was added to *Evolution* with the release of the Fallen Kingdom Dinosaur Update. The species becomes available to Jurassic World operations by progressing through the Science Division on Isla Sorna, and can subsequently be researched and found in the Morrison Formation and the Cleveland Lloyd Dinosaur Quarry dig sites.

## History

*Allosaurus* was originally intended to be displayed as an attraction in Jurassic Park on Isla Nublar. However, they hadn't been cloned at the time of the 1993 incident, with a 1996 asset catalogue of the dinosaurs present on Nublar and InGen's Site B facility on Isla Sorna, reported that a mere twelve percent of the *Allosaurus* genome had been completed.

Subsequently, however, *Allosaurus* specimens were bred for Jurassic World on Isla Nublar, after it opened to the public in 2004. Given the presence of juvenile *Allosaurus* on the island in 2018, it is likely that a breeding population existed on Isla Nublar. During the eruption of Mount Sibo in 2018, one juvenile *Allosaurus* was encountered during a stampede of dinosaurs. Several *Allosaurus* were transported off the island to the mansion home of Benjamin Lockwood in California. At least one was successfully sold at the Lockwood Manor auction, while the others were released into the wilds of northern California alongside numerous other species of dinosaur by Maisie Lockwood.

A year after the events at Lockwood Manor, a fully mature *Allosaurus* was encountered in Big Rock National Park, where it was witnessed unsuccessfully hunting a family of *Nasutoceratops*. Subsequently, the predator turned its focus to a family of campers in a trailer, causing severe damage before being frightened away by a crossbow bolt fired by the camper's daughter Kadasha.

Four years after the incident at Lockwood Manor, an adult *Allosaurus* and a juvenile *Allosaurus* were present in the illegal Amber Clave Market of Valletta, Malta. The juvenile *Allosaurus* was seen fighting a juvenile *Baryonyx*, while the adult *Allosaurus* was freed from its cage and roamed the streets of Valletta alongside an adult *Carnotaurus*.

## Characteristics

One of the most fearsome dinosaurs ever to have roamed the earth, *Allosaurus* is a large, ferocious theropod dinosaur. Weighing up to 2.5 tons and measuring around 12 meters in length, it is one of the largest carnivores in the *Evolution* series. It bares exaggerated crests and spines running down its back. An unusually large number of fossil specimens also makes *Allosaurus* one of the best studied dinosaurs of all time. Its name translates to "*Different Lizard*". The apex predator of the Late Jurassic period, *Allosaurus'* enormous skull contains rows of large, serrated teeth for tearing flesh, while its long, powerful tail helps it to balance. Notable features of the *Allosaurus* are a very strong skull and the ability to open its jaws extremely wide. However, it had a relatively weak bite force, unlike the largest theropods. The base genome of the *Allosaurus* is a blueish-grey body, a cream underbelly, light grey stripes covering its entire back, and a pair of red brow crests above its eyes.

## Gameplay

### *Evolution*

#### Behaviour

*Allosaurus* is a large, solitary theropod that doesn't tolerate other large carnivores in their enclosure, even other *Allosaurs*, which can result in potentially fatal clashes. However, they can tolerate a decent number of other species in their enclosure, including small carnivores and herbivores. *Allosaurus* prefer large areas of open grassland to hunt in and prefer comparatively smaller areas of forest. The comfort threshold of the *Allosaurus* is high, comparable to *Giganotosaurus*, requiring powerful fences to be contained.

## Paleontology

*Allosaurus* was one of the largest and most prolific predators of the Late Jurassic, found in North America and Portugal. While the first incomplete *Allosaurus* fossils were discovered in 1869, the first official discovery of *Allosaurus* fossils came in 1877, when Othniel Charles Marsh found fragments of an unknown dinosaur in Colorado, during the "*Bone Wars*" between Marsh and Edward Drinker Cope. At the time, the fossils were so unlike any previously found dinosaur bones that Marsh named it *Allosaurus*, meaning "*Different Lizard*". Two years later, more fossils were unearthed by H. F. Hubbell, although the quality of the near-complete skeleton was not realized until 1908, after Cope had died. Major operations in the 1960s then uncovered over 45 specimens at the Cleveland Lloyd Dinosaur Quarry. With thousands of fossils emerging in the intervening years, *Allosaurus* fossils are now among the most commonly discovered dinosaur bones. *Allosaurus* was widespread throughout North America, yet despite its success, its branch from the Allosauridae seems to haven't evolved any further beyond the Late Jurassic. However, relatives such as *Acrocanthosaurus*, *Carcharodontosaurus*, and *Giganotosaurus* continued to thrive into the Cretaceous.

The bite of *Allosaurus* wasn't very strong and instead, it is theorized to have used its upper jaw like a hatchet to exsanguinate its prey, although the possibility of this hunting technique is still debated. It is also believed that *Allosaurus* also used its muscular, clawed arms to grapple onto its prey. It is often inferred to have been a pack hunter due to the large size of its prey and the existence of a number of "lair" sites with remains from several individuals found close together, earning it the popular moniker of "the lion of the Jurassic". However, other evidence also shows these animals were frequently aggressive to one another and even scavenged carcasses of their own species.

### Paleoecology

*Allosaurus* lived around 150 million years ago in the western United States - most notably Utah and Colorado - in the Morrison Formation, which at the time was semiarid conifer forest environments with river-lining ferns, both distinct wet and dry seasons, and flat floodplains. Life would have been supported by river-lining ferns and conifer forests throughout both wet and dry seasons. *Allosaurus* co-existed alongside dozens of other species of dinosaur, including the sauropods *Diplodocus*, *Apatosaurus*, *Brachiosaurus*, and *Camarasaurus*, other herbivores such as *Dryosaurus*, *Nanosaurus*, *Camptosaurus*, and *Stegosaurus*, as well as carnivores such as *Ceratosaurus*, *Ornitholestes*, and the large theropod *Torvosaurus*.

## Behind the scenes

*Allosaurus* first appeared in 2018's *Jurassic World: Fallen Kingdom* in juvenile form. Instead of directly using the movie asset like they did with the rest of the *Fallen Kingdom* dinosaurs, the development team built a completely new model depicting a fully grown *Allosaurus*, loosely based on the juvenile from the film. Audio files provided by Universal Pictures, however, were still used.

In 2019, the film canon design of an adult *Allosaurus* appears for the first time in *Battle at Big Rock*, which bears minimal resemblance to *Evolution's Allosaurus*. Despite there being an update dedicated to the short film, the *Allosaurus* in-game wasn't updated to be film accurate.
