Description
Original diagnose after Guinot et al. (2014) p. 72 [20107]: Orectolobiform teeth higher (up to 1 mm) than wide showing minor degree of monognathic heterodonty. Main cusp and pair of cusplets triangular and lingually oriented. Marginal region of cusplets bend toward the main cusp with converging apices. Strong labial crown depression between main cusp and cusplets. Additional pair of incipient cusplets rarely present. Well-developed oval-shaped apron oriented basally and strongly overhanging the root. Short margino-lingual faces separated from wide and rounded medio-lingual uvula by a short notch. Root hemiaulacorhize, low, with flat basal face. Poorly developed root branches separated by a medio-labial depression with two foramina. Presence of a mediolingual and a pair of margino-lingual foramina. Lateral teeth with wider crown, shorter and slightly bifid apron more inclined basally and better developed root branches.
