Description
Original diagnose after GUINOT, CAPPETTA & ADNET, 2014 [20107]: Echinorhinid teeth with weak degree of gradient monognathic heterodonty. Teeth labio-lingually compressed and wider (up to 1.8 mm) than high, except in symphyseal teeth. Main cusp of sigmoid profile, distally inclined, not extending beyond the distal root edge in lingual view. Mesial heel oblique and slightly convex with concave contact with main cusp. Distal heel subhorizontal and straight to convex. High anaulacorhize root with flat basal face. Basal face sub-rectangular in basal or lingual views with slightly concave margino-lingual edges and V-shaped mediolabial edge. Lingual root face reduced with slight margino-lingual depressions. Labial root face flat to slightly convex. Numerous lingual and labial nutritive foramina. Presence of erect mesiodistally compressed symphyseal teeth.
