Cephalopod limestone biofacies in the Silurian of the Prague Basin, Bohemia

The biostratinomy of Silurian cephalopod limestone biofacies of the Prague Basin is interpreted. Two facies types are recognized. One is the result of a surface current and the other one is the effect of redeposition within the current itself in a shallower environment during storm events. Orientation of cephalopod shells in these two facies types is discussed in relation to the Prague Basin development and to phenomena like telescoping, trap-structures and geopetal structures
