The herbivorous dinocephalians are characterized by pronounced thickening of most bones of the skull, and while some palaeontologists believe that this thickening was of little adaptive significance and perhaps even pathological, another theory maintains that the thick skull bones indicate that dinocephalians were head-butting animals, as are some living reptiles and mammals.
