Current identification/main database link: Gavelinella ammonoides (Reuss, 1844)
Original Description
[Google Translated from German]: Circular, flat, deepened in the middle at the top, curved at the circumference, strongly umbilical at the bottom. The thread is concave, consisting of 3 distinct turns, each with 7 chambers. The last ones are strongly arched, the others less so, incidentally very narrow, somewhat crooked and curved, each ending in a small pointed tongue at the bottom towards the navel, which partially covers the neighboring one. The shallow seams are curved in an arc at the top and do not quite reach the outer edge, but this occurs on the lower surface where they are more straight.

Extra details from original publication
[Google Translated from German]: It is very similar to the Rosalina lorneiana d'Orbigny, 1840, but differs in the numerous very narrow, flat, less inclined, curved chambers and the very shallow seams. Very rare.
