Umzamba River Mouth Caves (Cretaceous of South Africa)

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

• coordinate estimated from map

• outcrop-level geographic resolution

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

Environment/lithology: marginal marine; poorly lithified siliciclastic sediments

• JA: apparently poorly lithified because (1) specimens were collected from "walls and ceilings" of caves; (2) figured specimens retain matrix; and (3) other outcrops "are hard and [their] fossils are difficult to extract"

Size class: macrofossils

Collection methods: surface (in situ),
