Length (L) and width (W) are measured as the smallest circumscribed rectangle with sides parallel and perpendicular to the reference line (indicated by triangles). A. Upper dentition (M1–M3): 1–12, tubercle (1–12); 1, anterostyle; 2, lingual anterocone; 1bis, 2bis, accessory cusps; 3, labial anterocone; 4, enterostyle; 5, protocone; 6, paracone; 7, posterostyle; 8, hypocone; 9, metacone; 12, posterior cingulum. B. Lower dentition (m1–m3): a, medial anteroconid (= tma); b, labial anteroconid; c, lingual anteroconid; d, protoconid; e, metaconid; f, hypoconid; g, entoconid; h, posterior cingulum; i, longitudinal spur; j, posterior accessory cuspid; k, accessory cuspids on the labial cingulum; l, posterior complex.
