Echinodon
''Echinodon'' (pronounced eh-KY-no-don) meaning "hedgehog tooth" in reference to the spines on its teeth (Greek εχινος, ''echinos'' = hedgehog + όδους, ''odous'' = tooth), occasionally known as ''Saurechinodon'', is a genus of small European dinosaur of the early Cretaceous Period (Berriasian age), 140 million years ago.
==Discovery and species==
The type specimen was discovered by Samuel Beckles in the Purbeck Beds near Swanage, England. A bipedal herbivore, it was around long. Unlike most ornithischians, ''Echinodon'' had one or two caniniform teeth in each maxilla.
The only species is ''E. becklesii'', named in 1861 by Richard Owen, who mistook it for a lizard. Remains of an ''Echinodon''-like animal were found in stratigraphic zone 4 of the Morrison Formation.〔Foster, J. (2007). "Appendix." ''Jurassic West: The Dinosaurs of the Morrison Formation and Their World''. Indiana University Press. pp. 327-329.〕 These are now named ''Fruitadens''.
