Hippodraco is a genus of medium sized ornithopod dinosaur that lived in North America during the early Cretaceous. Though still a fairly large dinosaur when compared to a person, Hippodraco paled in comparison to the impressively large Iguanacolossus, which is known from the same member of the Cedar Mountain Formation that Hippodraco was found in, strongly suggesting that the two genera lived in same approximate ecosystems at the same time. Hippodraco would have fed upon low to medium height plants while keeping a lookout for predatory theropod dinosaurs.
