Description
Original diagnosis after Lund, Grogan & Fath, 2014 [21751]: Moderate sized petalodont with narrow compressiform neurocranium; basis cranii distinctly wider than dorsal aspect, well_mineralized hyoid complex and elements of a nested branchial arch skeleton. Dentition of regionally specialized anterior and lateral teeth; median upper double the width of the bifid median lower, three anterior lower teeth, five small upper lateral tooth families and probable three lower families.
