Time
Cretaceous Late Campanian
Classification
Ornithischia Genasauria Cerapoda Marginocephalia Pachycephalosauria Pachycephalosauridae [Pachycephalosaurinae]
Diet
Herbivore
Fossilsite
Kirtland Formation or Kirtland Shale, De-na-zin Member. (= \\\\\\\"upper shale member\\\\\\\"), San Juan Basin > San Juan Co. > Bisti/De-na-zin Wilderness Area > Willow Wash > NMMNH locality L-3921, New Mexico, US
Fall Under
Sphaerotholus buchholtzae
Info
Skull
Sphaerotholus buchholtzae (Williamson & Carr, 2003) > Sphaerotholus goodwini (Williamson & Carr, 2003)
Holotype
NMMNH P-27403: Skull dome lacking facial and palatal bones
Hypodigm
APK:50/0: NMMNH P-30068 nearly complete left dentary w/ squamosal and cranial fragments, in addition to holotype skull dome.
The skull was discovered by Paul Sealey, an adjunct naturalist at the museum during a collecting trip led by Williamson in the spring of 1998. \\\\\\\"Sphaerotholus,\\\\\\\" from the Greek words for \\\\\\\"ball\\\\\\\" and \\\\\\\"dome,\\\\\\\" the species name, is a reference to Goodwin, who works at the University of California Museum of Paleontology in Berkeley.
Possible subjective synonym of Prenocephale

Diagnosis
Parietosquamosal bar (in caudal aspect) reducing in depth laterally, to lesser extent than in Sphaerotholus buchholtzae. parietalreduce to thin slip between squamosals (Williamson and Carr, 2003)
