Stratigraphy
| Formation: | Kotick Point | ||||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Kotick Point Fm, which is regionally overlain by the Whisky Bay Fm (Albian-Coniacian). AGE: Aptian-Albian, on the basis of ammonite biostratigraphy; here placed in the Albian on the basis of stratigraphic position. STRATIGRAPHIC POSITION: From beds throughout the section. | |||||

Collection methods and comments
| Collection excludes: | some genera |
| Collection methods: | survey of museum collection |
| Reason for describing collection: | biostratigraphic analysis |
| Collection method comments: COLLECTOR: Multiple collectors, including J.A. Crame and M.R.A Thompson. REPOSITORY: Not stated, but presumably British Antarctic Survey and Oxford University Museum (OUM). | |
| Taxonomic list comments:COVERAGE: Not exhaustive but inclusive of representative and biostratigraphically important ammonoidea, bivalvia, and other taxa. Other taxa may be present, but were not listed in present biostratigraphic treatment. NOMENCLATURE: Not an authoritative publication, but with fairly modern nomenclature and species-resolution identifications where listed. | |
