The Muschelkalk (German: shellbearing limestone, French: calcaire coquillier) is a sequence of sedimentary rock strata (a lithostratigraphic unit) in the geology of central and western Europe. It has a Middle Triassic (10 million years ago) age and forms the middle part of the Germanic Trias, that further consists of the Buntsandstein (lower part) and Keuper (upper part). The Muschelkalk consists of a sequence of limestone and dolostone beds. In the past the time span in which the Muschelkalk was deposited could also be called Muschelkalk. In modern stratigraphy however, the name only applies to the stratigraphic unit.
