Species Pseudotropites subsalinarius WÄHNER

The casings are evolute. The WQ is wider than high and trapezoidal. Already at a dm of approx. 17 mm, a broad keel and furrows are clearly developed. After a pronounced nodule stage, wide, high ribs appear, which are retroradiate with a slight bend forward. The splitting into secondary ribs and their course over the external side, typical for small specimens according to Wähner, could not be observed so far. The ribs bend slightly forward near the external side and abut the secondary keels at an obtuse angle. Keel, secondary keels and furrows are quite distinct.

* Description according to Kment (2000), supplemented


Very similar in sculpture is Schreinbachites retroversicostatus, which, however, is clearly distinguished by the missing nodule stage.
Alpinoceras salinarius, which has a comparable WQ, has much weaker and more curved ribs. There is also a difference in the lobe line (s.Wähner).
The specimen pictured here is strikingly similar to the larger one illustrated by Wähner.


Dimensions at D= 44mm (according to Kment):
Nw % v. D: ca. 52%
Wh % v. D: ca. 25%
Wb % v. D: ca. 30%
