Description
Original diagnosis after Siverson (1993) p. 6 [2213]: A large, dentally primitive Squalus. Centrally situated apron: triangular in juveniles, but often well demarcated with parallel edges in adults. Lingual side of apron not covered by basal edge of root. Mesial expansion of basal edge of tooth root very poorly developed, particularly in juveniles. Basal face of root flat or slightly concave in profile. Axial foramina fused into large subcircular infundibulum. Teeth only moderately labio-lingually compressed.
