Diagnosis
ReferenceDiagnosis
Z. J. Tseng et al. 2009large mustelid, with very prominent sagittal crest similar to older individuals of the eurasian badger (Meles Boddaert 1785); infraorbital foramina small, immediately above posterior root of P3 as in most basal mustelines; upper tooth formula 3/1/3/1/; i3 unenlarged, as in basal muste- lines; P2-3 slender and simple, without accessory cusps; P4 protocone posteriorly offset from parastyle crest, slightly an- terior in position to paracone, similar to Martes Frisch 1775; carnassial notch absent as in all neomustelids, P4 paracone very robust, labially and lingually inflated, invading the proto- cone space; P4 hypoconal crest absent as in basal mustelines; M1 triangular in occlusal view, with well-formed, straight lingual cingulum; posterior cingulum slightly expanded, M1 labial roots close together or fused, intermediate between the morphology observed in basal mustelines and lutrines.
