Etymology Reptile de Parks (à cause de William Parks, qui le baptisa pour la première fois)

Parksosaurus is a genus of neornithischian dinosaur from the early Maastrichtian-aged Horseshoe Canyon Formation of Alberta, Canada. It is based on most of a partially articulated skeleton and partial skull, showing it to have been a small, bipedal, herbivorous dinosaur. It is one of the few described non-hadrosaurid ornithopods from the end of the Cretaceous in North America, existing around 70 million years ago.
