Summary

[edit]
Description
Deutsch: Löcher fossiler, mariner Bohrmuscheln, „Pholaden“, im aufgeschlossenen Massenkalk eines Brandungsfelsens eines untermiozänen Meeres zwischen Alb und Alpen (Gesteinsschichten der „Oberen Meeresmolasse“ des Molassebeckens, heute in ca. 585 m NN). Die Typlokalität im Dorf Heldenfingen (Gerstetten, Ostalb) - ein Naturdenkmal mit felsiger Abrasionsplattform - belegt das im Gelände als markante Stufe streckenweise erkennbare, durchgängig nachgewiesene Kliff des letzten Molassemeeres. Die Röhren in denen die Bohrmuscheln lebten, haben einen Durchmesser von 0,5-2 cm, weiter oben in der Steilwand eher 3 cm bei einer Länge von ca. 8 cm. Es handelt sich offensichtlich um verschiedene Generationen von Pholadenröhren.

English: Tubular burrows of marine bivalve mollusca (Pholadidae). They use a teethy shell to grind away at rock to create tubular burrows. The type area is a Naturdenkmal in the village Heldenfingen, (Gerstetten, Eastern Alb). It denominates the rocky cliff of the Lower Miocene sea („Upper Marine Molasse]]“ of the Molasse basin), which is documented across the Swabian Alb from west to east. The Pholad borings, measure 0,5-2 cm at the top of the rock and 3 cm at the bottom. The borings obviously represent several generations.
