Tylocephale

Tylocephale (meaning "swollen head", from the Greek τυλη meaning 'callus' or 'hard swelling' and κεφαλη meaning 'head') is a genus of pachycephalosaurid dinosaur from the Late Cretaceous period. It was a herbivorous dinosaur estimated to have been about 1.4 metres (4.6 ft) in length. It had the tallest dome of any known pachycephalosaur.

Tylocephale lived during the Campanian stage, around 75 million years ago. It was discovered in the Khulsan region of Mongolia. The type species is T. gilmorei, described by Teresa Maryańska and Osmólska in 1974.[1]

The pachycephalosaurids evolved in Asia and then migrated into North America, thus it is likely that Tylocephale migrated back into Asia. It is closely related to Prenocephale[2]
