NMB Loc. 15809 - Rio Gurabo [Gurabo Fm] (Miocene of Dominican Republic)

Where: Dominican Republic (19.5° N, 71.2° W: paleocoordinates 19.5° N, 70.6° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Gurabo Formation, Messinian (7.2 - 5.3 Ma)

• STRATIGRAPHIC RELATIONS: From the Gurabo Formation, which unconformably overlies the Cercado Formation, and is unconformably overlain by the Mao 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: unit G8 (360-387 m), sample ca. 380 m above base.

• bed-level stratigraphic resolution

Environment/lithology: perireef or subreef; lithified siliciclastic sediments and lithified limestone

• deeper (more than 10-20 m), more turbid reef habitats
• slump deposits of reefal carbonates

Size class: macrofossils
