About this book

This is a study of the stratigraphical occurrences of non-ammonoid cephalopods in the Late-Silurian-Middle Devonian. More than 2000 cephalopod specimens were collected from a section in the Tafilalt of south-east Morocco for the study. For the first time, non-ammonoid cephalopod occurrences were recorded against a precisely controlled stratigraphical record in post-Lochkovian Devonian sediments.
