Thescelosaurus thesihluh-SORRUHS

Thescelosaurus ( ) is a genus of ornithischian dinosaur that lived during the Late Cretaceous period in western North America. It was named and described in 1913 by the paleontologist Charles W. Gilmore; the type species is T. neglectus. Two other species, T. garbanii and T. assiniboiensis, were named in 1976 and 2011, respectively. Additional species have been suggested but are currently not accepted. Thescelosaurus is the eponymous member of its family, the Thescelosauridae. Thescelosaurids are either considered to be basal (“primitive”) ornithopods, or are placed outside of this group within the broader group Neornithischia.

Adult Thescelosaurus would have measured roughly 3-4 long and probably weighed 200 – 300 kg. It moved on two legs, and its body was counter-balanced by its long tail, which made up half of the body length and was stiffened by rod-like ossified tendons.
