Cercado de Mao - Bluff No. 3 [Cercado Fm] (Miocene of Dominican Republic)

Where: Dominican Republic (19.5° N, 71.0° W: paleocoordinates 19.5° N, 70.1° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Cercado Formation, Tortonian (11.6 - 7.2 Ma)

• STRATIGRAPHIC RELATIONS: From the Cercado Formation, which unconformably overlies the Baitoa Formation, and is unconformably overlain by the Cercado Formation. AGE: Late Miocene, based on Table 1 of Saunders et al. (1986); late Miocene according to Jung (1994, p. 260); direct date from Cheetham et al. (1999). STRATIGRAPHIC POSITION: Bluff approximately 200 ft thick.

• group of beds-level stratigraphic resolution

Environment/lithology: offshore; poorly lithified, blue claystone

• No paleoenvironmental data reported by Maury.
• Bluff composed of blue clays and sand with layers of marl. Tellinas abundant. Fucoids and Bryozoa in the sandy layers.

Size class: macrofossils

Preservation: original aragonite

Reposited in the PRI

Collection methods: quarrying,
