Homalocephale (from Greek omalos, homalos, "even", and kephale, kephale, "head") is a genus of dinosaur belonging to the pachycephalosaurid family, which lived during the late Cretaceous period of what is now Mongolia, 80 million years ago. The genus was described in 1974 by Osmolska & Maryanska, and consists of a single species, H. calathocercos, though this may be a synonym (and juvenile form) of Prenocephale. Homalocephale was 1.8 metres (6 ft) long and herbivorous.
