Current identification:
Translated using Google translate from German. Original text below Diagnosis: The type species of the genus Eoceratobulimina n. Gen. With the following special features: Deep in the umbilical region there is down-pulling end chamber. Description: Test small; oval, in the sutures little lobate, round outline. Dorsal side, low trochospiral. Ventral view barely concave, the insignificant navel is almost completely obscured by deep-drawn parts of the end chamber. Spiral side, the chambers of the juvenile section are difficult to separate, later they are separated by sunk and always clearly recessed seams; altogether not quite two turns observable. To five to six chambers on the underside, separated by slightly curved seams. The orifice grove still taken over by the Triassic ancestors (in the interior of the chamber probably still formed as a more or less complete arcus developed bulge) very clearly, at least partly open to the two previous chambers. Very rare. Translated using Google translate from German. Original text below Distribution: In the upper Callovian type locality seemingly very isolated
Original Description
Description: Gehäuse klein; ovaler, in denSuturen wenig lobater, runder Umriß. Dorsalseite niedrig trochospiral, Ventralansicht kaum konkav gedellt, der unbedeutende Nabel wird durch tief herabziehende Anteile der Endkammer fast völlig verdeckt. Spiralseitig sind die Kammern des Jugendabschnittes schwer zu trennen, später sind sie durch versenkte und immer deutlich nach hinten gebogene Nähte gesondert; insgesamt nicht ganz zwei Windungen beobachtbar. Bauchseitig fünf bis sechs Kammern zu sehen, durch leicht geschwungene Nähte getrennt. Die von den triassischen Ahnen noch übernommene Mündungsfurche (im Kammerinneren wahrscheinlich noch als mehr oder minder vollständiger, arcus entwickelte Wölbung ausgebildet) sehr deutlich, auch noch beizwei vorhergehenden Kammern zumindest teilweise offen. Sehr selten.
