Description
Original diagnosis after Hodnett, Elliott, Olson & Wittke, 2012 [16123]: Large teeth measuring up to 30mm mesiodistally with large, broad median cusp. Main lateral cusps are broad, lower than median cusp and located on mesial and distal extremities of tooth base. A single intermediate cusp is located between median and lateral cusps. All cusps lack cristae. Coarse carinae present on median and lateral cusps. Tooth base trapezoidal, deep, broad and with rounded edges. Two separate, rounded, button-like orolingual ridges. Two rounded basolabial projections. Basolabial depression moderately developed.
