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

Wikipedia has a more detailed and comprehensive article on Hypsilophodon

Jurassic Park novelEdit

"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 "Hypsilophodon" 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 it appeared in the novels.

The Lost WorldEdit

Hypsilophodon was first seen on the marshy plain by the river to the south with the other herds of dinosaurs. The Hypsilophodons were described as medium-sized, dark-green, lizard-like or gazelle-like animals, having perhaps 20 members in its herd, and intermittently poking their large heads up above the grass along the river.

Later on, as Sarah Harding regained consciousness and made her way through the island's jungle she encountered a herd of panicked, dark-green, lizard-like animals about four feet high that were running and leaping away from an attacking Velociraptor pack. Their panicked cries were reminiscent of yelping dogs. One of the animals knocked Sarah to the ground, but Sarah escaped the stampede by climbing onto a tree branch. One of the animals was taken down by the raptor pack. Based on their description, the animals in the herd were most likely Hypsilophodon.
