Allosaurus was a large predatory bipedal dinosaur that lived during the late Jurassic period, roughly 155 to 145 million years ago. A. fragilis was the first species discovered, described by Orthniel Charles Marsh in 1877.
Allosaurus grew from 30-35 feet, with large specimens growing to 39 feet--roughly the same size as some large Tyrannosaurus--with a skull 3 feet in length filled with dozens of sharp, serrated teeth. It was a "typical" theropod dinosaur, bipedal with strong, long legs and a long thick tail. It's arms were long, though short in proportion to it's legs and powerful, ending in three clawed fingers. It also had three primary toes, with a fourth vestigial "dewclaw". It also possessed a pair of horns above the eyes, varying in size between individual Allosaurus. The horns were extensions of the skull covered by keratin to protect the bone and blood vessels, their function believed to be for combat between individual Allosaurus.
The Allosaurus has, to date, only appeared in Dino Crisis 2 (during the game it is inaccurately depicted as looking like a downsized or young Tyrannosaurus). It is a large predator, something of a middle ground between the small and agile Velociraptor and the slow, powerful Tyrannosaurus, serving as the most powerful non-boss enemy in the game. The Allosaurus is described as an active predator, hunting Velociraptor and present where large populations of Velociraptor may roam. It's head is heavily armored, capable of being highly resistant gunfire up to and over pistol rounds and buckshot rounds. To maximize this advantage, the Allosaurus uses it's agility to keep its head constantly in front of its prey. This threat is doubled, as Allosaurus work in numbers. Despite these strengths, the Allosaurus is vulnerable to fire attacks from Flamethrowers and higher-caliber weapons such as the Anti-Tank Rifle and Heavy Machine Gun. In one section of the game, an onslaught of Allosaurus attack the player, who's only relief is the use of artillery support. Towards the end of the game, an Allosaurus also kills David Falk. It also makes an appearance in the game Namco X Capcom as an enemy.
Dino Crisis 2: Extra CrisisEditAllosaurus is playable in Extra Crisis. It boasts average speed and decent attack power. In Dino Duel mode, Player 2 gets an Albino Allosaurus if they select it.
- The Allosaurus is portrayed incorrectly in game, where it's depicted as simply as a downsized version of the Tyrannosaurus. In real life it was built much more lightly.
