Description
Original diagnosis after Hodnett, Toomey, Egli, Ward, Wood, Olson, Tolleson, Tweet & Santucci, 2024 [32664]: Small- to medium-sized teeth measuring between 5–21 mm mesiodistally. Median cusp flat labially and convex lingually, as broad as tall and triangular with 18–25 cristae on labiolingual margins, with anterior positioned teeth more erect and mediolaterally positioned teeth recurved posteriorly. Lateral cusps flare from the base with 7–8 cristae, approximately half the height of the median cusp, and broad at the base. Single intermediate cusp between the median and lateral cusp approximately three-quarters as tall as the lateral cusp. Tooth base is reniform in shape, slightly concave labially, with a well-developed lingual torus. Orolingual projections consisting of two well-developed, relatively robust, elliptical pads positioned between the median cusp and the lingual rim of the tooth base. Basolabial projections of two well-developed, relatively robust, elliptical pads. Basolabial depression moderately developed and triangular in shape.
Palatoquadrate otic process is dorsoventrally deep and less expanded craniocaudally. Articular process of the quadrate directed ventroposteriorly. Palatine ramus short and deep. Meckel’s cartilage dorsally concave and ventrally convex with a well-developed mandibular knob and short retroarticular process. Hyomandibula strap-like, with shallow anterior depression and triangular posterior facet.
