The ornithopod looks most similar to a hypsilophodont, heterodontosaurid, or dryosaurid, small, two-legged, herbivorous ornithopods. Some popular guesses to this creature's identity include Hypsilophodon, Othnielia, and Dryosaurus. However, the ornithopod's true identity remains unconfirmed.
During CIA agent Daniel Espinoza's time on Isla Nublar, he was briefly captured by some of Cazares' men. As he was being brought to the Visitor Center by jeep, he passed by a man carrying the likely recently tranquilized ornithopod on his shoulder.
It is unknown what happened to the ornithopod after the defeat of Cazares. As Dr. Francis White freed all of Cazares' captured dinosaurs, it is likely that it survived and continued living on Isla Nublar.
