Diagnosis
ReferenceDiagnosis
G. G. Simpson 1927p4 is not molariform, but is transversely compressed, with high central cusp, now truncated by wear, a very small anterior accessory, cusp, and a heel with a small median posterior cusp united to the main cusp by a crest. There is a slightly developed basin internal to this crest (on the internal half of the heel),but external to it there is a lateral concavity with no approach to a basined condition. There were three molars of subequal size, the last with the posterior root elongated. The jaw is very slender, with a well-delimited masseteric fossa, its anterior border swollen. There is a relatively large and very distinct posterior mental foramen beneath the anterior root of M2.
