Homalocephale was a pachycephalosaurid dinosaur from the late Cretaceous period. The name 'Homalocephale' is derived from the Greek 'homalos', meaning 'even', and 'kephale', meaning head, and refers to the dinosaur's low-domed skull. This skull differentiates Homalocephale from dinosaurs like Pachycephalosaurus, which exhibit a highly thickened cranial roof.It has been suggested that both high and low domed dinosaurs made use of their heads (and strong supporting pelvises) for defense, with high-domed dinosaurs tending towards head butting behavior, and low-domed dinosaurs tending towards using their heads to push. Another interpretation is that these flat-headed pachycephalosaurids are simply juveniles of other species.
The genus and species Homalocephale calathocercos was described in 1974 by Teresa Maryańska and Halszka Osmólska, two Polish paleontologists who specialize in Mongolian dinosaurs. At the same time, Maryańska and Osmólska also described the genus and species Prenocephale prenes. There are suggestions that Homalocephale calathocercos and Prenocephale prenes could just be different ages or genders of the same species, but Maryańska and Osmólska noted enough anatomical differences between that they considered them different taxa.
Homalocephale lived in what is modern day Mongolia, which nowadays is mainly dry deserts, but at the time would have meant a habitat consisting of high altitude forests. Pachycephalosaurid diets are not well documented, but they are largely considered to be herbivorous, possibly omnivorous, with a diet including plants and insects. As researchers have noted a variety of wear patterns on pachycephalosaurid teeth, we do at least know that diets varied significantly from species to species.
