Genus Tropacerithium Gründel, Keupp & Lang, 2019

Type species.

Tropacerithium cumaritum Gründel, Keupp & Lang, 2019; upper Kimmeridgian; South Germany.

Remarks.

Deviating from the diagnosis of the genus given by Gründel et al. (2019), the few specimens presented here for Tropacerithium have around 5 somewhat reinforced spiral cords on the whorl face, with 2 weaker ones running in between. The intersections of the stronger spiral cords with the axial ribs are weakly knobby.
