Original description:

Beschreibung: Die distale Platte besitzt einen relativ schmalen, deutlich gezahnten Aussenrand, der aus etwa 15-20 Zähnchen besteht. Das Zentralfeld ist von radial angeordneten Elementen bedeckt und weist im Zentrum eine kleine runde Öffnung auf. Auf der dorsalen Seite lassen sich 10-12 <<Speichen>> erkennen. Diese Form wurde in einzelnen Exemplaren im Schacht Rossenray I Horizont C2, im Schacht Hoerstgen Horizont D und im Septarienton von Freien- walde gefunden.

Translation (from Google translate, 2021)
Description: The distal plate has a relatively narrow, clearly toothed outer edge, which consists of about 15-20 small teeth. The central field is covered by radially arranged elements and has a small round opening in the center. 10-12 "spokes" can be seen on the dorsal side. This form was found in individual specimens in the Rossenray I shaft Horizon C2, in the Hoerstgenshaft Horizon D  and in the septarian-clay of Freienwalde.
