Eutriconodonta Kermack, Mussett & Rigney 1973

EUTRICONODONTA Kermack, Mussett & Rigney, 1973 (Fig. 32A, B, E, F) DESCRIPTION Some mammalian teeth show a distinctive morphology comprising three main cusps placed serially in anteroposterior alignment on a transversely compressed crown (Fig. 32A, B, E, F). This cusp arrangement and general morphology is typical of eutriconodontans (Kielan-Jaworowska et al. 2004). Orientation of these isolated teeth follows the criteria of Godefroit & Battail (1997). The most convex side of the crown is considered to be the labial face, and the most concave the lingual face. Accessory cusps are usually more numerous or better developed on the distal side, and thus the side bearing the most developed and/or the most differentiated accessory cusps is considered to be distal. The distal inclination of the cusps, when present, also helps to distinguish the mesial and distal faces of the teeth.
