Tylocephalonyx is an extinct chalicothere from the Miocene of North America.

Description[]

Tylocephalonyx is notable for its dome-shaped skull. It may have used its "dome" in the same way as the pachycephalosaurs, though there is no clear evidence to link either pachycephalosaurs nor Tylocephalonyx to using their domes as battering rams.^[2] Tylocephalonyx is related to the modern horse, rhino, and tapir.^[3]
