Description
Original diagnosis after Hodnett, Toomey, Egli, Ward, Wood, Olson, Tolleson, Tweet & Santucci, 2024 [32664]: Small- to medium-sized teeth measuring between 7–23 mm mesiodistally. Median cusp biconvex and relatively broad and triangular with 12–15 cristae on labiolingual margins, more erect in anterior positioned teeth and recurved posteriorly in mediolaterally positioned teeth. Lateral cusps flare from the base with 5–6 cristae, approximately a quarter the height of the median cusp, and bulbous at the base. Intermediate cusps vary in size and number with 1–4 cusps between the median and lateral cusp that can be half as tall or as tall as the lateral cusp. Tooth base trapezoidal, slightly concave labially, with a weakly developed lingual torus. Orolingual projection a thin rectangular ridge. Basolabial projection a thin ridge along the basolabial margin. Basolabial depression moderately developed and triangular in shape. Numerous nutrient foramina present on the labial margin between basolabial rim and crown.
