Prehistoric Models: Ornithopoda

The ornithopoda meaning “bird foot” are a group of herbivorous dinosaurs that first appear in the early Jurassic, and went extinct at the end of the Cretaceous period. Many are bipedal and run on their hind legs, while some of the larger species walk on all four (quadrapedal). The most famous members of this group are the thumb spiked Iguanodonts and the numerous hadrosaurus or as they are more commonly known the “duck billed dinosaurs”.
