Thescelosauridae

Doolysaurus is an extinct genus of thescelosaurid ornithischian dinosaur known from the Cretaceous (Albian–lower Cenomanian) Ilseongsan Formation of South Korea. The genus contains a single species, Doolysaurus huhmini, known from the partial skeleton of a small juvenile individual. It is the first named South Korean dinosaur with diagnostic cranial material, providing important insight into the early evolution of thescelosaurid ornithischians in East Asia, and the second named basal neornithischian from South Korea after Koreanosaurus.
