Yangchuanosaurus

Yangchuanosaurus is a theropod dinosaur thought to be related to Allosaurus. Two species have been discovered: shangyouensis and magnus. These dinosaurs lived in the Late Jurassic of China. It is said to have hunted in packs.

In Jurassic Park (film)
Yangchuanosaurus is not seen in the movie. But on the map of the park and next to a vial in the Cold Storage Room the name Metriacanthosaurus is shown. According to vertebrate paleontologist this was probably meant to refer to Yangchuanosaurus, which was then classified as a species of the Metriacanthosaur genus (click here for a detailed discussion).

In Jurassic Park inspired games

 * Yangchuanosaurus can be created from paleo-DNA in the game Jurassic Park III: Park Builder.
 * In Jurassic Park: Operation Genesis, Yangchuanosaurus was one of the many dinosaurs mentioned to have been in the game, but wound up being cut (possibly replaced by Allosaurus). Still, its name still appeared on an in-game file.
