Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| P. E. Morse et al. 2019 | Differs from Teilhardina and ‘Archicebus’ in having relatively wider lower teeth with more well-developed cingulids, particularly the buccal cingulid of M1-2, in having a more molarized P4 with a relatively taller metaconid and small, distinct paraconid, in having a more inflated hypoconulid lobe on M3, in possessing transverse cristae and more strongly expressed preparacristae on the P3-4, in having upper molars with continuous lingual cingula and weak enamel crenulation, in possessing a weak Nannopithex fold on M1-2, and in possessing a more inflated, longer protocone on M3. Differs from Tetonoides (i.e., Tetonoides pearcei: Beard et al., 1992; Williams, 1994; Williams and Covert, 1994) in lacking a paraconid on P3, in having a narrower P4 with a lower metaconid relative to the height of the protoconid and shorter talonid basin, and in having a smaller, particularly shorter, M3 relative to M2. Differs from Anemorhysis in having a less molarized P4, with less basined talonid, lower protoconid, and more medial cristid obliqua, and in typically having a less hypertrophied I1. Differs from Tetonius in being smaller, with relatively narrower lower premolars and molars, and in having larger C1 and P2. Differs from Omomys in being smaller, having a relatively shorter P4 with a narrower talonid basin, buccal cingulid, and taller paraconid above the pre- protocristid, and in having a relatively smaller M3. Differs from Chumashius in being smaller, lacking a metaconid on P3, lacking a well-developed mesiolingual cingulid on P3-4, having a buccal cingulid on P3-4, and having a relatively shorter M3. |
