Hodson Loc. 185 - La Vela, Falcon [Mataruca Mbr, Caujarao Fm] (Miocene of Venezuela)

Where: Venezuela (11.5° N, 69.6° W: paleocoordinates 11.2° N, 67.9° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

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

• LITHOSTRATIGRAPHY: From the Mataruca Member of 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: From unknown position within section.

• 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.
