Stegosaurus

Stegosaurus was a stegosaur that lived in North America from 150 to 140 million years ago, during the Late Jurassic period. Its most famous specimens come from the Morrison Formation, in Colorado.

In Jurassic Park
While seen in The Lost World: Jurassic Park, and Jurassic Park III, the name "Stegasaurus" (A typo, obviously,) was seen next to a vile in the cold storage room in Jurassic Park.

In Operation: Genesis
Stegosaurus was also in the game for PS2, PC, and Xbox, Jurassic Park: Operation Genesis, as a three-star attraction. Its fossils are found in the Morrison Fomation, just like in the real world.
