Diagnoza The elements P1 are very variable and difficult to determine. Generally, the platform is wide, flat and relatively thin, with a strong occlusal omamentation of the ribs. The margin in some elements is crenulated but in others remains smooth.
Porównanie There is a remarkable variability in element shapes, some being close to juveniles of Dinodus lobatus. Most of the P1 elements attributed to this species are strongly angular and bent at the cusp so their basal surface is concave. Some juvenile specimens have their platform linear in profile and may represent yet another related or convergently similar species.
