This rather variable species is characterized by dense, sigmoidal ribbing and rather narrow umbilicus. It occurs in the "Oolithenbank" of SW Germany and in eastern France (Guerin-Franiatte, 1 990, pi. 20, Fig. 2). The Complanata Subzone at Limekiln Steps is at least 1 6m thick; the true thickness may be greater because the lower boundary is not yet precisely located. The upper portion of the subzone, here indicated by S. ex gr. striatissirna, is extremely thin compared with SW Germany. Depressa Subzone (Ammonites see PI.
