| Coordinates: | 38.4° South, 177.3° East (view map) |
| Paleocoordinates: | 80.3° South, 177.5° East |
| Basis of coordinate: | based on nearby landmark |
| Geographic resolution: | outcrop |
Time
| Period: | Cretaceous | Epoch: | Early Cretaceous |
| 10 m.y. bin: | Cretaceous 2-3 | ||
| Key time interval: | Late Aptian | ||
| Age range of interval: | 119.5 - 113 m.y. ago |
Stratigraphy
| Formation: | Koranga Sandstone | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: From Koranga Sandstone of the Taitai Series, overlies Torelsse supergroup along Maccoyella Ridge and is unconformably overlain by the the Te Wera Sandstone. THICKNESS: From bed within formation that varies in thickness between 116 (at this area) and 76 m (locally). AGE: Korangan of Wellman (1956) = Upper Aptian based on presence in unit of Aucellina radiatostriata and Maccoyella reflecta (Day 1969, Day and Speden 1970). STRATIGRAPHIC POSITION: From c. 40-100 ft above base of section. | |||||
Lithology and environment
| Primary lithology: | pebbly lithified siltstone |
| Includes fossils? | Y |
| Lithology description: SPECIFIC LITHOLOGY: Hard, non-calcareous pebbly siltstone. LITHIFICATION: Lithified, based on facies description. | |
| Environment: | coastal indet. |
| Glacial or sequence phase: | transgressive |
| Geology comments: ENVIRONMENT: Accumulated in shallow-water, high-energy environment. | |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
Collection methods and comments
| Collection methods: | selective quarrying,field collection |
| Reason for describing collection: | biostratigraphic analysis |
| Museum repositories: | IGNS |
| Collection method comments: COLLECTOR: I.G. Speden. 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. | |
