Proceratosaurus

Proceratosaurus was a primitive coelurosaurian Theropod that lived in Europe in the early Jurassic Period. It looked somewhat similar to the later Ceratosaurus, for which it is named after, but only due to also having a hornlike crest. Overall, Proceratosaurus was a much more gracile and delicate animal.

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 namesake, Ceratosaurus, appeared in Jurassic Park III.
