Description
Original diagnosis after Li, Sun, Cuny, Ji, Jiang & Zhou, 2021 [30105]: Heterodont dentition with teeth showing a rather flattened crown, which is basally arched on the anterior teeth, but straight on the posterior teeth. The main cusp is moderately developed and flanked by lateral cusplets on the anterior teeth. The lateral cusplets are reduced on the lateral and posterior teeth. A blunt occlusal crest crosses the crown mesiodistally. There is a lingual peg at the base of the main cusp. The crown is ornamented by nearly parallel ridges and honeycombed pits. There is a deep groove at the crown–root junction and a labial depression on the basal face of the root showing unroofed canals.
