Description
Original diagnosis after Feichtinger, Pollerspöck, Harzhauser, Auer, Ćorić, Kranner, Beaury & Guinot, 2024 [32635]: Tiny teeth with pronounced heterodonty. Straight and strongly lingually projected main cusp flanked by one pair of lateral cusps in anterior teeth, distally inclined main cusp flanked by one or two distal cusplets; a variable number of fused mesial cusplets in lateral teeth. Lingual crown face convex with long enameloid folds, labial face concave with coarse, parallel and short enameloid folds at the crown base. Moderate mediolingual root protuberance, flat and flared basal root face protruding. Strongly concave margino-lingual root faces in basal view; concave labial root face. Medio-lingual foramen on lingual protuberance and one pair of margino-lingual foramina present. Medio-labial foramen accompanied by one pair of marginal foramina.
