Proceratosaurus

Proceratosaurus was a primitive ceratosaur Theropod that lived in Europe in the early Jurassic Period. It looked somewhat similar to its later relative, Ceratosaurus, for which it is named after.

In Jurassic Park
Proceratosaurus does not show up in the movies in person, but its name is both on a map and next to a vial in Jurassic Park. Its descendant, Ceratosaurus, appeared in Jurassic Park III.
