Calvarius (meaning "suffering") is an extinct genus of styracosternan ornithopod from the Late Cretaceous (Maastrichtian age) Talarn Formation of Spain. The genus contains a single species, Calvarius rapidus, known from a single metatarsal. The slender morphology of this bone may indicate Calvarius had a cursorial (adapted to run) ecology, in contrast to its slower-moving relatives.
