Rio Codore, 5.4 km N of Urumaco [Urumaco Fm] (Miocene of Venezuela)

Where: Falcon, Venezuela (11.2° N, 70.3° W: paleocoordinates 11.0° N, 68.8° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Upper Member (Urumaco Formation), Late/Upper Miocene (11.6 - 5.3 Ma)

• LITHOSTRATIGRAPHY: From the Urumaco Formation, which overlies the Socorro Formation (Middle-Late Miocene) and is overlain by the Codore Formation (late Miocene-early Pliocene). From the upper member of the Urumaco Formation on the basis of geographic position (Hendy et al., unpublished data). AGE: Late Miocene, based on recent foraminiferal biostratigraphy (Smith et al., 2010) and Sr analyses (Hendy et al., unpublished data); upper Middle Miocene in Hodson & Hodson (1931).

• formation-level stratigraphic resolution

Environment/lithology: marine; unlithified siltstone

• LITHOLOGY: Not stated, but most fossiliferous assemblages in Middle Urumaco are from siltstone facies. LITHIFICATION: Not stated, but most fossiliferous assemblages in Middle Urumaco are unlithified.

Size class: macrofossils
