Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| Q. Jiangzuo et al. 2023 | Diagnosis: Large to huge ailuropodine bear, moderately hypercarnivorous in dental features, and exhibiting substantial sexual dimorphism. Cranial condylobasal length 380–515 mm. Mandible often with premasseteric fossa. I1/I2 with large posterocentral accessory cusp and reduced posterolateral cusp; I3 and canines large and robust; anterior premolars (P1–3/p1–3) present, occasionally lost in numbers in Huracan schneideri, H. roblesi, and Huracan coffeyi; P4 with large parastyle and variably (intraspecifically) subdivided hypocone; M1 slightly trapezoidal in shape; M2 equals M1 in length, each with slightly developed talon; p4 with distinct anterior and posterior cingulid cusps, but lacks medial ridge; and m1 with elongate paraconid, and distinct metaconid and mesoconid.
Differential diagnosis: Huracan differs from Indarctos, a paraphyletic assemblage of more basal taxa representing the nearest outgroups to a clade of the new genus plus Agriotherium, by having generally larger size (except I. oregonensis of similar size), upper I1/I2 with large posterocentral accessory cusp, P4 with larger parastyle, M2 with distinctly shorter talon, p4 with stronger anterior and posterior cingulid cuspids, m1 with more elongated paraconid, and presence of mandibular premasseteric fossa; Huracan differs from Agriotherium, its sister group, by generally larger size, and with upper I1/I2 with large posterocentral accessory cusp, P4 with more frequently subdivided hypocone, M1 more elongated, M2 with generally longer talon, p4 often with Mandible often with premasseteric fossa. I1/I2 with large posterocentral accessory cusp, P4 with more frequently sub- divided hypocone, M1 more elongated, M2 with generally longer talon, p4 often without distinct medial ridge, and m1 with presence of large metaconid and two smaller entoconids. |
