Lithology and environment
Primary lithology:very coarse lithified argillaceous sandstone
Includes fossils?Y
Lithology description: SPECIFIC LITHOLOGY: Muddy grit. LITHIFICATION: Lithified, based on facies description.
Environment:offshore
Glacial or sequence phase:transgressive
Geology comments: ENVIRONMENT: Offshore marine, mid-outer shelf paleoenvironment.
Taphonomy
Modes of preservation:body,cast,mold/impression
Size of fossils:macrofossils
Collection methods and comments
Collection methods:surface (in situ),field collection
Reason for describing collection:biostratigraphic analysis
Museum repositories:IGNS
Collectors:Wellman Collection dates:1953
Collection method comments: COLLECTOR: H. W. Wellman, 1953. 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.
