Hypsilophodon lived in the Cretaceous period in Europe, and was very similar to the earlier Othnielia, which lived only in North America.

Jurassic Park novel

"Hypsilophodontids" and "hypsilophodonts" are one of the several species of Dinosaur featured in the Jurassic Park novel. But these titles not necessarily refer to the Hypsilophodon genus.

When Gerry Harding captures a "Hypsilophodont" this information is given:

In the harsh quartz lights, the hypsilophodont's green head hung down out of the sling, the tongue dangling, the eyes dull. ... The hypsy was a small dryosaur, seven feet long, weighing about five hundred pounds.[1]

This means that Dryosaurus is the only genus of which we can be sure appeared in the novels.
