Fossil snails of the genus Trochactaeon from Kainach near Voitsberg, Styria, Austria (Gosau-Group of Kainach, upper Cretaceous) - Summary of this years prospection Introduction Snails of the extinct genus Trochactaeon (formerly part of the genus Actaeonella) are among the most familiar fossils of the upper Cretaceous Gosau-Group of the Austrian Alps. The rather large size of some species (>10 cm), their intriguing spiral pattern in transverse sections and plenty supply, based on many mass occurrence, make them particularly popular. Some well known occurrences in Austria, di- 13 replies

Hello! I have collected quite many specimens with Trochactaeon snails from April to May 2020.

Some of the specimens contain abundant black, wavy, "folded", shell fragments. They seem to grow on the Trochactaeon snails in some places. They resemble small oysters in some ways. Unfortunately, I have not found anything conclusive about their identity. I found a pic in a paper of Kollmann (2014), with some somewhat similar, unidentified b

Fossil hunting in the Geistthal-formation (Santonian - lower Campanian), Gosau basin of Kainach, Styria, Austria
FranzBernhard posted a topic in Fossil Hunting Trips
Fossil hunting in the Santonian - lower Campanian Geistthal-formation of the Gosau basin of Kainach, Eastern Alps (Styria, Austria) As a whole, the Gosau basin of Kainach - St. Bartholomä is not very fossiliferous. In contrast to the St. Bartholomä-formation with its rudists etc., the other, much more extensive formations, especially the very extensive, somewhat tubititic Afling-formation, are generally very poor in fossils. Some are known, eg. ammonites, but their occurrences are rather elusive. One exception - or at least in part - are Trochactaeon snails. They are kn- 9 replies
