El Hatillo (Miocene of Venezuela)

Also known as Urumaco

Where: Falcon, Venezuela (11.2° N, 70.2° W: paleocoordinates 10.9° N, 68.8° W)

• coordinate stated in text

• outcrop-level geographic resolution

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

• The geological units from which the specimens were obtained are the middle and upper members of the Urumaco Formation of Venezuela. These units have been recently summarized in the Léxico estratigráfico de Venezuela (1997).

• member-level stratigraphic resolution

Environment/lithology: fluvial-deltaic; brown, gray claystone and sandstone

• The paleoenvironments are interpreted as inner sub-littoral and coastal lagoon enviroments with riverine and estuarine influence (Díaz de Gamero, 1996).
