Locality O, Venezuela - Weisbord (1964) (Pliocene of Venezuela)

Also known as Locality O

Where: Sucre, Venezuela (10.0° N, 63.0° W: paleocoordinates 9.9° N, 62.3° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Catia Member (Playa Grande Formation), Early/Lower Pliocene (5.3 - 3.6 Ma)

• The Playa Grande Formation consists of a variegated assemblage of rocks and atarts at the base with a brown conglomerate. It attains a maximum thickness of 65 ft at its type locality. The deposit is lenticular lying with a pronounced unconformity on the Las Pailas Formatiion. The Catia Member is exposed north of the Bruscas Fault. The Playa Grande and Mare formations of the Cabo Blanco Group are believed to be early Pliocene in age, and the Guaiguaza clay late Pliocene.

• bed-level stratigraphic resolution

Environment/lithology: marine; unlithified, brown, yellow siltstone and fine-grained, medium, gypsiferous, calcareous sandstone

• Beds were laid down in shallow marine waters
• The Catia Member consists mainly of siltstones, sandstones, and conglomerates, whcih are interbedded with coquinas, and occasional mudstone, and sporadic limestone.

Size class: macrofossils

Preservation: original aragonite

Reposited in the PRI

Collection methods: quarrying,

• Collected by Weisbord in 1955 and 1956. Collections also held at Flordia State University
