Orodromeus is a genus of hypsilophodont dinosaur form the Campanian stage of the Late Cretaceous Period (75 million years ago). It lived in what is now North America in the state of Montana. The type species, O. makelai, was described by Horner and Weishampel in 1988.
It is believed that Orodromeus was a burrowing dinosaur much like its relative Oryctodromeus, based on the positioning of the bones within the area the fossils were found.
Orodromeus was featured in the third episode of the Discovery Channel’s TV series Dinosaur Planet. It has been portrayed as living in herds and was hunted by Troodon.
