Peishansaurus was a genus
of plant-eating dinosaur
that lived during the Late Cretaceous
period (Campanian

Peishansaurus was named by Bohlin in 1953 from a fragmentary jaw with some teeth. The type species
is P. philemys. Peishansaurus is a doubtful genus; it is either an ankylosaur or a pachycephalosaur, but further details are unknown.
