†Ornithopoda

Taxa	Presence	Location	Description	Images
Camptosaurus	Kimmeridgian to ?Berriasian	Wyoming, USA; England; France	Camptosaurus could be more than 7.9 meters long (26 ft), and 2.0 meters tall (6.7 ft) at the hips. They had heavy bodies but, as well as walking on four legs (quadrupedal), could also rear up to walk on two legs (bipedal). This genus is probably closely related to the ancestor of the later iguanodontid and hadrosaurid dinosaurs. It probably ate cycads with its beak.	Othnielosaurus
