  • 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.
  • Includes 16 plates and 23 text-figures.
