3.5 km N and 3? W of El Picache on up side of Chiguaje Fault (Miocene of Venezuela)

Also known as Urumaco

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

• coordinate based on nearby landmark

• small collection-level geographic resolution

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

• bed-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).
• The middle member of the Urumaco Formation consists of claystone and sand. The gray claystone is microfossiliferous, and the brown claystone contains vertebrate remains such as reptiles, mammals, marine and freshwater fish, and also coprolites and wood (Díaz de Gamero & Linares, 1989). The limestone changes from conchiferous sandstones to consolidated coquina limestone. In the lower half of this middle member, an abundant and diverse marine mollusk fauna exists in a sandy matrix. This matrix also contains elasmobranch teeth and teleostean otoliths.

Size class: macrofossils
