Dome function Tylocephale has been noted for its prominent dome, a trait shared by other pachycephalosaurids, which was covered in keratin. The dome function of Tylocephale itself has not been analyzed in detail, but a similar dome of Prenocephale was tested by biologists Eric Snively and Adam Cox in 2008.
