| Summary: | The Hunsrück Slate fossils were typically found during roof slate mining. However, in the vicinity of Birkenfeld and Kirschweiler, in the south-western spur of the Central Hunsrück Basin, it is possible to collect fossils from natural exposures (brook respective road cut). Unlike the famous Bundenbach fossils, these finds are not pyritized and their preservation is three-dimensional. At Birkenfeld the fossils are enclosed in quartz-concretions. This locality yielded a mixed fauna with elements from the Rhenish Normal Facies and Herzynic Facies; at Kirschweiler the fauna belongs to the shallower Normal Facies. The dominant fossils are brachiopods, trilobites, crinoids, orthocone nautiloids, snails and corals. Rare fossils from Birkenfeld include parts of phyllocarid crustaceans and fishes, bivalves, conulariids, tentaculitoids and ammonoids. The index-fossils (especially the brachiopods) allow determination to species level and correlation with the upper Ulmen substage. The lithology and faunal composition have been used to reconstruct paleoecology. Photo: C. Schumacher |
| Reaction 1: | De Baets et al. (2013), in their paper "Emsian Ammonoidea and the age of the Hunsrück Slate (Rhenish Mountains, Western Germany)" in Palaeontographica, Abt. A, Volume 299, Issues 1-6: 1-113, state that the ammonite and dacryoconarid finds indicate a Nowakia praecursor to N. barrandei age for the Birkenfeld locality. The brachiopod finds might indicate an Ulmen to Vallendar age. |
