Hypsilophodon

Hypsilophodon lived in the Early-Mid Cretaceou period of every continent, and was very similar to the earlier Othnielia, which lived only in North America.

In Jurassic Park
Hypsilophodon was one of the several species of Dinosaur featured in the Jurassic Park novel. It was probably in the same paddock as the Othnielia, given how much they were alike.
