  abstract  = {The invertebrate trace fossils from the Keuper (Upper Triassic) of the southern part of the Germanic Basin are revised. The Keuper sediments of the Germanic Basin are predominantly composed of rocks representing various nonmarine environments dominated by red-bed facies. The W{\"u}rzburg Formation, the Stuttgart Formation, and the Hassberge Formation, all representing deposits of extended river systems, contain the richest ichnofauna. Trace fossil abundance is generally low and their occurrence is scattered. The studied material can be assigned to 28 ichnogenera, 38 ichnospecies, and 6 vernacular forms. Among the described trace fossils are one new ichnogenus and three new ichnospecies. Apart from the revision of the invertebrate trace fossils from the Keuper numerous related ichnotaxa from various localities and ages have been studied and revised. In the course of these studies several ichnotaxa are synonymised, lowered in rank, and new ichnogenera, subichnogenera, and ichnospecies are suggested. In addition, general guidelines for naming, and methodologies for studying invertebrate trace fossils are presented. The palaeoecology of three ichnocoenoses, one from the W{\"u}rzburg Formation and two from the Hassberge Formation in Lower Franconia are briefly discussed.},

  abstract  = {The present study concerened with taxonomy and palaeoecology of the Cenomanian-Turonian macrobenthic fauna which includes bivalves, gastropods, echinoids, and coral. In addtion, cephalopods are also taken in consideration. 144 taxa are identified and systematically described. Palaeoecological and taphonomic anylsis of the statistically sampled macrobenthos are also discussed. The biostratigraphic sequences along the Cenomanian-Turonian rocks were carried out on the basis of ammonites and other macrobenthic fauna such as corals and bivalves. In order to reconstruct benthic association, 41 statistically sampled were subjected to cluster ananlysis by using Past Programm (Hammer et al., 2001). 10 association and three assemblages were described in order to reconstruct the different depositional enviroments.},
