Stratigraphy
| Formation: | Te Wera Sandstone | ||||
| Regional section: | Te Wera Sandstone | Regional bed: | 175 ft | ||
| Regional order: | bottom to top | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: From Te Wera Sandstone of the Taitai Series, overlies Torelsse supergroup along Maccoyella Ridge and is unconformably overlying by the the Koranga Sandstone. THICKNESS: From bed within formation that varies in thickness between 91-183 m (regionally). AGE: Urutawan of Wellman (1956) = Middle to Upper Albian based on presence in unit of Aucellina gryphaeoides (Day 1969, Day and Speden 1970). STRATIGRAPHIC POSITION: From 175 ft above base of formation. | |||||
Lithology and environment

| Includes fossils? | Y |
| Lithology description: SPECIFIC LITHOLOGY: Conglomerate breccia. LITHIFICATION: Lithified, based on facies description. | |
| Environment: | coastal indet. |
| Glacial or sequence phase: | transgressive |
| Geology comments: ENVIRONMENT: Shallow marine, inner shelf paleoenvironment. | |
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. | |
