Also known as GS5396

Where: New Zealand (38.4° S, 177.3° E: paleocoordinates 75.2° S, 170.6° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Karekare Siltstone Formation, Urutawan (108.4 - 103.3 Ma)

• STRATIGRAPHIC RELATIONS: From Karekare Siltstone of the Taitai Series, which conformably overlies the Te Wera Sandstone (Albian). AGE: Urutawan of Wellman (1956) = Middle to Upper Albian, on the basis of macrofossil biostratigraphy. STRATIGRAPHIC POSITION: From 40 ft above base of formation.

Taxonomic list

• 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.
