Texacephale is a genus of basal pachycephalosaurid dinosaur from the Campanian stage of the Late Cretaceous. The type species is Texacephale langstoni; its fossils were discovered in the Aguja Formation and described in 2010 by Longrich, Sankey and Tanke. The generic name means Texas + "head" (cephale in Greek) in reference to its place of discovery, and the specific name honors Wann Langston.[1]
Discovery
The holotype specimen of Texacephale, LSUMNS 20010, is composed of fused frontals and parietals. A second specimen, LSUMNS 20012, is composed of an incomplete frontoparietal dome.[1] According to the team, the fossilized dome of the animal possessed a pair of flanges on the sides of the skull. The team interpreted these structures as "gears" that would help deal with stress on the bone during head-butting,[2] a hypothetical behavior that has been challenged by other authors in recent years.[3][4]
