Locality 1 (Upper), Umzamba River mouth (Cretaceous of South Africa)

Where: South Africa (31.1° S, 30.2° E: paleocoordinates 48.3° S, 15.7° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Umzamba Formation, Santonian (86.3 - 83.6 Ma)

• STRATIGRAPHIC RELATIONS: From the Umzamba Fm, which regionally overlies the Albian-Coniacian Mzinene Fm. THICKNESS: Unknown bed and section thickness. AGE: From Santonian, though the section ranges from the Coniacian to at least the Santonian, possibly Campanian based on ammonite biostratigraphy. STRATIGRAPHIC POSITION: From middle and upper beds within formation.

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithified siltstone

• ENVIRONMENT: No detailed environmental data reported in text.
• SPECIFIC LITHOLOGY: Unknown lithology, presumably with siltstone matrix based on lithologies of adjacent beds. LITHIFICATION: Lithified, assumed on the basis of facies descriptions from regionally dominant lithology, and figures from subsequent publications (e.g. Kennedy and Kinger 1977).

Size class: macrofossils

Collection methods: COLLECTORS: Material described by van Hoepen (1921). REPOSITORY: Teyler Museum.

Taxonomic list

• COVERAGE: Includes ammonites, brachiopods, bivalves and gastropods. Abundance data may only apply to ammonites. NOMENCLATURE: Some of faunal list derived from authoritive publications, although for the most part this is not the case and taxa lack subgeneric or species-level designations. Nevertheless, authors are specialists and nomenclature appears fairly accurate and modern.
