Tenontosaurus

This was an early member of the plant-eating family of dinosaurs that includes Iguanodon. It had a very long tail compared to other members of its family. Instead of front teeth, it had a beak, and it walked on all four feet most of the time.

This dinosaur was originally found as a partial skeleton in 1903. The genus was not named, however, until the early 1960's. By that time, parts of more than 20 individuals had been discovered. It had at least 59 caudal vertebrae in its long tail. One specimen was found with Deinonychus teeth associated with it, leading to the conclusion that Tenontosaurus was fed upon by this predator, which probably hunted it in small packs.

Jurassic Park
In the first issue Dr. Alan Grant and Dr. Ellie Sattler had found Tentotosaurus fossils and Dr. Grant theorizes that these bones were the last meal of a pack of Velociraptor (which is actually a reclassified Deinonychus in this comic series) that they had just found.
