Description
Original diagnose after Engelbrecht et al. (2017) p. 181 [25551]: Extinct dalatiid shark defined by the following combination of lower tooth characters: very compressed lower teeth, with a low, convex and rather broad crown, which slightly is inclined towards the rear; mesial and distal cutting edges coarsely serrated; distal heel also with coarse serrations; distal cutting edge nearly vertical; mesial cutting edge comparatively longer than distal cutting edge and slightly concave to more or less straight; the distal heel is convex and low; short, broad, convex, and bifid apron; uvula absent; root mesio-distally compressed, with well separated root lobes; articular facets are restricted to upper part of root.
