Taxonomic list

• Authors imply that they are relying at least in part on the observations of other scientists as to what cephalopod fauna is present. They also concentrated on cephalopods and blastoids, mentioning there were other taxa present (brachs, bryozoans, corals, etc.) but made no effort to ID or list them except one tabulate coral.
