( Fig. 32E, F ) DESCRIPTION The specimen ANG M-02 ( Fig. 32E, F ) consists of an almost complete tooth, only lacking the mesial root. The crown is labiolingually compressed and bears three mesiodistally aligned cusps. A main central cusp a is largely dominant. It is triangular in lateral profile and surrounded by two smaller accessory cusps: cusp c (distal) reaches half of the height of cusp a, and cusp b (mesial) is about three times smaller than cusp c. Cusp a is slightly flexed lingually. Cusps a and c bear distolingually oriented wear facets. Both labial and lingual cingulid are present. Thus, considering these characters, ANG M-02 can be identified as an eutriconodontan left lower premolariform. It is somewhat similar to the p3 of Triconodon from the Berriasian of Britain ( Jäger et al. 2021 ), so the specimen is tentatively referred to this genus.
