The body of the allosaur designs used in the films was allegedly based on the common species Allosaurus fragilis, but the skull anatomy was based on Allosaurus jimmadseni (which was, at the time, classified as A. fragilis). Because the skull anatomy is the primary means of differentiating these two species, Jurassic-Pedia has chosen to classify the species appearing in the films as A. jimmadseni.

Over the years the park experiences years of growth and prosperity, along with many new dinosaur editions over the years. Soon the Pteranodon eggs would hatch and the aviary would be built by at least 2012. By 2004, the first strands of Mosasaurus DNA was uncovered and later in 2007, the first Mosasaurus was created for the park. Also in 2007, a new Brachiosaurus was added to the park and Stegosaurus was also added this year. In 2009, a new Carnotaurus was added to the park. By 2010, InGen unveiled the Apatosaurus to the park, as well as add in a new Baryonyx that same year. By 2011, the first Stygimoloch was created, proving that the animal was separate from its cousins, Dracorex and Pachycephalosaurus. By 2012, the first group of Velociraptors were starting to be bred for a top secret project posing as a test exhibit. In 2014, Sinoceratops was introduced to the park. [10] By 2015, the number of species had grown hugely on the island, featuring animals such as Allosaurus, Ceratosaurus, Dimorphodon, Edmontosaurus, Metriacanthosaurus, Microceratus, Monolophosaurus, Nasutoceratops, Ouranosaurus, Pachycephalosaurus, Pachyrhinosaurus, Peloroplites, Suchomimus, Tarbosaurus, Teratophoneus, and possibly others. [4] [11] However, despite the growing amount of dinosaurs in the park, investors got nervous as profits slowly declined. The investors urged the company to find a new solution to the park's problem. [12] Indominus rex [ ] HOWEVER, it is important to note that Ethan did not have final say on the design; he only offered advisement. In fact, Ethan has stated that the final design, though better than the original concept and among his favorite designs in the franchise, could still use tweaks; namely, a thinner head and longer arms. One of Universal's mandates that could not be changed: the spikes.Body language is also used to communicate with other species, and most likely one another. Gaping the jaws and assuming a threatening position can be used as an intimidation tactic, while an irked allosaur may shove or snap at other animals to warn them away. While it has not been directly observed, body features such as the lacrimal horns are most likely used for communication, such as identifying a particular allosaur. Ecological Interactions

Allosaurus was among the less propagandized species during the Mount Sibo controversy, with relatively little mention of it by the Dinosaur Protection Group. It was featured in at least one piece of promotional artwork in which it was used to illustrate the idea of many dinosaur species living in harmony. Allosaurus featured in DPG artwork. To help display which ones match up better, I have also roughly re-posed the skeletals' poses accordingly.In the Jurassic period, Allosaurus was affected by hematophagous pests such as early mosquitoes, which is how InGen was able to obtain its DNA. No studies have currently been performed to determine whether modern mosquitoes affect it in a similar way.
