Description
Original diagnose after Eastman (1911) p. 400 [752]: Type. Complete skeleton, Carnegie Museum (Cat. No. 4737). In general like the contemporary species of S. alifera, but distinguished from it by its smaller size (total length 49 cm ), relatively narrower disk, and more posterior position of both dorsal fins. The first dorsal arises at a point about one-third the distance between the hinder extremity of the pelvic fins and tip of the tail, the second dorsal midway between the latter point and origin of the first dorsal. Dentition and other characters as in the typical species. The differential characters given in the foregoing diagnosis are considered of sufficient weight to warrant a specific separation between the form here described and its larger contemporary which accompanies it in the same locality, S. alifera. Not more than two or three examples of the latter form have thus far been brought to light, so far as published information shows, and the holotype of the new species here made known is unique. Hence the genus Squatina must be regarded as represented very sparsely, and by not more than three species, at the time of its advent in the Upper Jura of Solenhofen.

Remarks
valid after Eastman (1911) p. 403 [752]; Eastman (1914) p. 399 [14497];
