Caujarao Formation (unspecified localities) (Miocene of Venezuela)

Where: Venezuela (11.0° N, 69.8° W: paleocoordinates 10.7° N, 68.2° W)

• coordinate based on nearby landmark

• basin-level geographic resolution

When: Caujarao Formation, Tortonian (11.6 - 7.2 Ma)

• LITHOSTRATIGRAPHY: From the Caujarao Formation, for which lithsotratigraphic relations are not discussed. AGE: Middle Miocene in Woodring (1982); Late Miocene according to Bolli (1970), Hunter (1978), and Jung (1989); Diaz de Gamero (1977) considered the unit to be correlated with the late Miocene Globorotalia acostaensis Zone [=Tortonian]. STRATIGRAPHIC POSITION: Collection is a composite for the formation.

• formation-level stratigraphic resolution

Environment/lithology: marine; siliciclastic sediments

• No paleoenvironmental data provided.
• LITHIFICATION: Unknown. LITHOLOGY: No lithologic data provided, but assumed to be siliciclastic.

Size class: macrofossils

Collection methods: quarrying,
