Collection methods and comments
| Collection methods: | surface (in situ),field collection | ||
| Reason for describing collection: | biostratigraphic analysis | ||
| Museum repositories: | IGNS | ||
| Collectors: | Gair et al | Collection dates: | 1966 |
| Collection method comments: COLLECTOR: H.S. Gair, M.R. Johnston, B. Simpson, and I.G. Speden, 1966. REPOSITORY: GSNZ (now GNS Science, Lower Hutt, New Zealand). | |||
| 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. | |||
