Texacephale
''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.
==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.〔 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,〔(Head-ramming dino had ‘gears’ in skull )〕 a hypothetical behavior that has been challenged by other authors in recent years.〔(Dinosaur Study Makes No Butts About It / Round-skull species didn't bash heads )〕〔(Cranial histology of pachycephalosaurs (Ornithischia: Marginocephalia) reveals transitory structures inconsistent with head-butting behavior )〕
