Der Soom-Schiefer, in der Fachliteratur häufig auch Soom Shale genannt, ist eine der wenigen Konservatlagerstätten des Ordoviziums. Die Lagerstätte findet sich in der Westkap-Provinz von Südafrika. Die Lagerstätte ist einzigartig, da sie sich auf 32° südlicher Breite befindet, aber in einer kühlen, glazial geprägten, marinen Umgebung entstand. 1967 wurden hier Brachiopoden und Trilobiten bekannt, die die erste unterpaläozoische Fauna waren, die aus Südafrika beschrieben wurde. Berühmt ist der Soom-Schiefer jedoch für seine außergewöhnliche Erhaltung von Conodonten. (de) The Soom Shale is a member of the Late Ordovician (Hirnantian) (Table Mountain Group) in South Africa, renowned for its remarkable preservation of soft-tissue in fossil material.Deposited in still waters, the unit lacks bioturbation, perhaps indicating anoxic conditions. It overlies the Pakhuis tillite and is overlain by the Disa Siltstone. It contains typical Ordovician microfossils, such as chitinozoa, acritarchs and spores, and its shelly fauna is also typical of this time period. Its macrofauna comprises pelagic organisms that sank rapidly to a barren sea floor. These include brachiopods, eurypterids, conodonts, nektaspids, trilobites and orthoconic cephalopods. (en) |
