Description
Original diagnose after Feichtinger et al., 2025 [34350]: Small teeth with marked dignathic heterodonty. Lower jaw teeth strongly labio-lingually compressed, higher than wide. Cusp of lower jaw teeth strongly bent distally with lingual root bulge extending throughout the entire crown width. Root bulge pierced by medio-lingual foramen; one pair of margino-lingual foramina present; central lingual foramen with faint nutritive grove occasionally developed. Wide apron in lower jaw teeth, covering one third of total tooth height. One pair of margino-labial foramina, occasion- ally accompanied by a variable number of smaller foramina. Medio-labial foramen opens below apron. Root morphology rectangular, not divided by nutritive groove. Upper jaw teeth symmetrical and monocuspid. Cusp triangular with sharp cutting edge, not reaching the apex or crown base. Lingual crown face strongly convex centrally, towards mesial and distal crown margin flat; faint striations in the middle of cusp developed. Labial crown face smooth and flat. Lingual root bulge pierced by medio-lingual foramen; central foramen with nutritive groove developed. Root morphology rectan- gular; basal root edge divided by nutritive groove. Labial root face with one pair of labial foramina.
