In Depth
Little is known about Wannanosaurus, but the skull specimen found appears to have been from a fully grown adult as the bones that make up the skull show signs of being fused together. Wannanosaurus is considered a primitive member of the pachycephalosaurs because it has a flat skull roof and enlarged openings when compared to other later pachycephalosaurs.
