Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. X. Samuels et al. 2018 | P2 broad and robust, and P4 enlarged with a broad paracone and metastyle; these features are typical of Gulo, but not observed in any other gulonines. P4 protocone anteriorly positioned and infraorbital foramen is oval, unlike Eira. P4 lacks an external median rootlet, unlike Pekania. P4 protocone and parastyle larger than in extant Gulo gulo and all other previously described species of Gulo. P4 parastyle includes a small, conical parastylar cusp. P4 metastyle tapers distally, unlike the posteriorly broad and squared metastyle of other Gulo species. P2 not as strongly reduced as in other members of the genus. Infraorbital foramen is located above the anterior root of the P4, rather than anterior to the P4 as is typical of other species of Gulo. |
