Description
Original diagnose after Guinot et al. (2013) p. 609 [24889]: Small teeth (less than 1mmwide) and moderate degree of gradient monognathic heterodonty. Crown with erect cusp and oval lower part of the labial face. Cutting edges in continuity with convex and inclined heels. Flat labial face of the lower part of the crown. Wide, convex (bifid in lateral teeth) and semicircular apron with a weak ridge following the outline of the apron from one marginal angle to the other; additional discontinuous ridge on the lower region of the labial face; apron not reaching the baseline of the tooth. Robust and trapezoidal lingual protuberance not reaching the lingual root edge. Concave profile of marginolingual faces with slightly flared basal region. Basal edge of the lingual face bearing a thin but sharp and continuous bulge, tapering near the marginal angles. Triangular root with well-marked lingual protuberance, concave marginolingual faces and rounded extremities. Main cusp directed to the posterior and displaced distally in lateroposterior teeth.
