Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| T. F. Flannery et al. 2022 | The molars of Bishops whitmorei differ from those of Ausktribosphenos nyktos in the m2 being the largest molar and the m3 being relatively small in size and in being more exaenodont and having a less extensive precingulid. The basal cingula on the lower molars are also reduced relative to those on A. nyktos (Rich et al. 2001). The posterior region of the posterior-most premolar consists of a broad talonid-like shelf that imparts a bilobed tooth profile in occlusal view. Bishops whitmorei specifically possesses six premolars, compared to five in A. nyktos. The dentary of B. whitmorei differs from that of henosferids and ausktribosphenids in having a greatly reduced Meckelian groove and no surangular or coronoid facet. The weak Meckelian groove is well separated from the mandibular foramen; this, together with location of the hypoconulid near the midline of the tooth and separated from the entoconid, renders B. whitmorei ‘more like the vast majority of placental mammals’ than A. nyktos (Rich et al. 2001, p. 7), or any other Mesozoic Southern Hemisphere tribosphenidan. |
