Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| C. S. Scott et al. 2016 | Differs from Purgatorius janisae in having significantly smaller and slightly lower crowned lower molars, with shorter trigonid relative to talonid, more gracile coronal morphology, and in having relatively more swollen lower molar cusps. Differs fur- ther from P. janisae in having better-developed posterior lobe on m3. Differs from Purgatorius coracis and P. unio (including P. titusi) in having lower molars slightly lower crowned, with shorter trig- onid relative to talonid, paraconid more inflated and distinct from longer and more transversely directed paracristid, and usually more lingual in position, and in having protoconid and metaconid with more swollen walls. Differs further in hypoconulid of m1– m2 being more robust and swollen, entoconid and hypoconid of m1–m2 more anteriorly positioned and posterior rim of talonid more arcuate (posteriorly convex), and in posterior lobe of talonid of m3 more sharply distinct from remainder of talonid, and hypo- conulid of m3 more strongly developed. |
