Description
Only one specimen has been found so far (in Kment 2021).
It has numerous, slender and high ribs which start at the umbilical wall, cross the flank retroradiatively and then bend sharply forward. They are highest at the outer edge of the flank and end abruptly at the middle of the external side, leaving a narrow furrow.
The ribs meet at about a 90° angle.
Compare
No other genera, such as Storthoceras, show such fine ribbing. The furrow on the external side is characteristic for Schlotheimia.
