Teilhardina belgica
Taxonomy
Omomys belgicus was named by Teilhard de Chardin (1927). Its type specimen is Ct.M. 64, a mandible (left mandible with P3, P4, and alveoli for I1, I2, C, and P2), and it is a 3D body fossil. Its type locality is Dormaal, which is in a Ypresian fluvial sandstone in the Tienen Formation of Belgium.
It was recombined as Teilhardina belgica by Simpson (1940), Gingerich (1977), Hooker (2007), Morse et al. (2019).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| P. E. Morse et al. 2019 | Differs from all other species of Teilhardina in having a mesial cingulum weakly present on P3, and in having the weakest M2 buccal cingulid. Further differs from T. brandti and T. asiatica in having a P3 paracone lower than that of P4 and weaker conules and cristae on upper molars, particularly the M premetaconule crista. Further differs from T. magnoliana and T. brandti, and resembles T. asiatica, in having an M2 trigonid of subequal width to the M2 talonid, as opposed to wider. |
