C. lambei (Sternberg, 1945) |
Colepiocephale was a genus of pachycephalosaurid dinosaur. The type species, C. lambei, was originally described by Sternberg (in 1945 as Stegoceras lambei), and later renamed by Sullivan in 2003.
C. lambei is a domed pachycephalosaur characterized principally by the lack of a lateral and posteriosquamosal shelf, a steeply down-turned parietal, and the presence of two incipient nodes tucked under the posterior margin of the parietosquamosal border.
Colepiocephale lambei has the arguable distinction of being the oldest known pachycephalosaurid, hailing from the middle Campanian; all other pachycephalosaurs were from the Maastrichtian. It lived in what is now Alberta, Canada.
