Turritellenplatte
From Wikipedia, the free encyclopedia
The Turritellenplatte of Ermingen ("Erminger Turritellenplatte" near Ulm, Germany) is a type of very rich fossil-bearing rock which is of particular interest to geologists and paleontologists. It occurs in a very restricted outcrop and is protected in its entirety as a natural monument.
This outcrop of these marine sedimentary rocks is situated in the northern part of the North Alpine Foreland Basin (NAFB) and it is famous for a superabundance of the shells of Turritella turris, a marine gastropod mollusk in the family Turritellidae. [1] The fauna of this gastropod-rich sandstone reflects mainly near-coastal and shallow marine conditions.[2] Petrographical and palaeontological data allow a correlation of the Turritellenplatte of Ermingen with Burdigalian (Lower Miocene). The Sr-isotope composition of shark teeth in the deposit suggests an age of about 18,5 Ma for the Turritellenplatte of Ermingen.[3]
