Also known as R 64

Where: Dominican Republic (18.4° N, 71.5° W: paleocoordinates 18.4° N, 71.4° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Pleistocene (2.6 - 0.0 Ma)

• STRATIGRAPHIC RELATIONS: Unknown lithostratigraphy. From sand in road. AGE: Undifferentiated Pleistocene. STRATIGRAPHIC POSITION: Unknown position within section.

• bed-level stratigraphic resolution

Environment/lithology: coastal; unlithified sandstone

• ENVIRONMENT: Environmental data not reported in text.
• SPECIFIC LITHOLOGY: Sand. LITHIFICATION: Unlithified, assumed on the basis of age and facies description.

Size class: macrofossils

Collected by Ross in 1919; reposited in the USNM

• COLLECTOR: C. P. Ross. REPOSITORY: Not stated, but numbers presumably correspond to USGS collections, hence probably reposited in USNM.
