Diagnosis
Reference | Diagnosis | |
---|---|---|
K. A. Kermack et al. 1998 | (based on the holotype only).- Upper tooth, probably mammalian, with three longitudinal rows of cusps, between which are two fluted basins. One basin contains the largest and deepest wear facet of the tooth. This basin is open at one end, where the largest cusp of the tooth occurs at the end of the marginal row. Between the other two rows of cusps is a smaller wear facet, which passes up on to the largest cusp. A third wea.r facet is detectable on the lateral edge of the tooth, on the same side as the large cusp. The roots are lost in the type specimen, but some of the referred specimens show divided, or partly divided roots. |
