Thescelosaurus

Thescelosaurus is a basal ornithischian (it would have been called a "hypsilophodont" in the 1980's) and among the last no-avialan dinosaurs. It's known from quite a few complete specimens - it's the third most common herbivore of the Hell Creek Formation, after Triceratops and Edmontosaurus.

It has a small beaked triangular head, smaller than normal for a dinosaur this size. Its body is long and heavily-built, its arms small and its legs sturdy. Like several other ornithischians, Thescelosaurus has intercostal plates, mineralized plates in between the ribs. It's slower than its relatives due to its heavy build. It ate low-to-the-ground plants in the humid forests it lived in.

Our Thescelosaurus live in the Hell Creek section. The group is close-knit and refuse to leave each others' sides, even for medical inspections (so obviously we inspect them all at once).
