Cercado Formation (unspecified localities) (Miocene of Dominican Republic)

Where: Dominican Republic (19.5° N, 71.2° W: paleocoordinates 19.4° N, 70.3° W)

• coordinate estimated from map

• local area-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). STRATIGRAPHIC POSITION: Composite list for formation.

• formation-level stratigraphic resolution

Environment/lithology: coastal; poorly lithified siliciclastic sediments

• ENVIRONMENT: Appearing to be shallow marine siliciclastic environment.
• SPECIFIC LITHOLOGY: Unknown, presumably silcicilastic. LITHIFICATION: Poorly lithified based on observation of figures.

Size class: macrofossils

Preservation: original aragonite, original calcite
