Abstract

The Upper Jurassic lithographic limestones of southern Germany have long been known for their exceptional preservation of decapod crustaceans (Glaessner, 1965), similar to the Upper Cretaceous of Lebanon (Hakel, Hadjoula) and the still poorly known Callovian strata at La Voulte-sur-Rhône (France). In these non-bioturbated limestones, the decay of decapod skeletons is reduced, so that besides the heavily mineralized chelae and carapace often even delicate structures such as pleopods and antennae are preserved. Recently, new decapod material has been obtained from both scientific and commercial excavations, in part in reopened lithographic limestone quarries.
