Sanshuilophus is an extinct monotypic genus of phenacolophid mammal that lived in East Asia during the Ypresian stage of the Eocene epoch.[1]
Description
The enamel microstructure pattern of the type species, Sanshuilophus zhaoi, was typical of a phenacolophid, with the inner Schmelzmuster containing prisms bounded into Hunter-Schreger bands (HSBs) while the outer layer consisted of prisms that were orientated either perpendicular or parallel to the enamel-dentine junction (EDJ). The species had bilophodont molars characterised by an absent mesostyle. Its premolars were sub-molariform in their morphology. Its body size was large compared to other phenacolophids, with the exception of the genus Zaisanolophus.[2]
