Lagerstätte
Sedimentary deposit with well-preserved extraordinary fossils
Lagerstätte
A Fossil-Lagerstätte (German pronunciation: [ˈlaːɡɐˌʃtɛtə] – from Lager 'storage, lair' and Stätte 'place'; pl. Lagerstätten) is a sedimentary deposit that preserves an exceptionally high amount of palaeontological information. Konzentrat-Lagerstätten preserve a high concentration of fossils, while Konservat-Lagerstätten offer exceptional fossil preservation, sometimes including preserved soft tissues. Konservat-Lagerstätten may have resulted from carcass burial in an anoxic environment with minimal bacteria, thus delaying the decomposition of both gross and fine biological features until long after a durable impression was created in the surrounding matrix. Fossil-Lagerstätten span geological time from the Neoproterozoic era to the present. Worldwide, some of the best examples of near-perfect fossilization are the Cambrian Maotianshan shales and Burgess Shale, the Ordovician Fezouata Biota, Beecher's Trilobite Bed, and Soom Shale, the Silurian Waukesha Biota, the Devonian Rhynie Chert...
