Jurassic Park Wiki

Tenontosaurus 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 packs.[1]

In Jurassic Park, Alan Grant mentions Tenontosaurus when he is explaining to Ian Malcolm about coordinated attacking behavior in raptors. He states that it would be one of the prey items that Velociraptor (reclassified Deinonychus in the novels) would hunt and kill.

Jurassic World: Alive

Tenontosaurus/JW: A

Tenontosaurus will be in Jurassic World: Alive. This will be the first time it has ever physically appeared in any Jurassic Park game. It inaccurately has a much shorter tail than in life.

Jurassic Park

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