Taxonomic list comments:COVERAGE: Exhaustive for bivalvia, and other invertebrate groups (cephalopoda, gastropoda, echinoidea, bryozoa, annelida listed). NOMENCLATURE: Not an authoritative publication, and generally lacking species-level designations. Identified by specialist (Speden), and lack of species names reflects poor preservation and insufficient existing taxonomic knowledge. |
