Description
Original diagnose after Reinecke et al. (2020) p. 113 [29177]: Small- to medium-sized pristiophorid teeth, up to 1.5 mm wide and ca 1.2 mm high. Teeth in supposedly anterior files with erect cusp and rather narrow, markedly sloping heels. Labial crown face strongly to slightly convex, with a vertical, axial ridge that extends from near the apex to the base; few subvertical folds on the labial face, mainly in lateral regions below the heels. Labial visor almost smooth to slightly ripply; apron moderately developed to strong. Sharp mesial/distal cutting edges at central cusp and on heels running continuously from apex to lateral crown margins. Laterolingual crown faces subvertical and rather high, smooth or weakly ornamented with faint folds or a transverse ridge. Uvula conical, broad, and moderately short to long. Root bulky and rather high, anaulacorhize, with broad axial depression on labial side. Teeth in lateral to lateroposterior files with erect or slightly oblique lower cusp and broader, less sloping heels. Labial crown faces less convex, invariably covered with an axial ridge, longer folds on faces below heels and some short, sharp folds on the labial visor. Apron broad and variably prominent. Uvula medium-sized to short and sometimes very narrow. Laterolingual crown faces smooth to slightly ripply. Root massive, almost as high as the crown. Commissural teeth with very low, narrow cusp, very short uvula and smooth crown surfaces.
