Beyond the game

The real Thescelosaurus

Thescelosaurus was a solidly built small ornithopod with a long tail and grasping forelimbs. Its skeleton records a relatively robust member of the small beaked dinosaur radiation.

Named skeletons document its head, forelimbs and body proportions. Those details distinguish it within the wider variety of small beaked ornithischians.
