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

Where: Dominican Republic (19.3° N, 70.8° W: paleocoordinates 19.1° N, 69.6° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Baitoa Formation, Early/Lower Miocene (23.0 - 16.0 Ma)

• STRATIGRAPHIC RELATIONS: From Baitoa Fm, which unconformably underlies the Cercardo, and overlies unconformably the Tabera Fm. AGE: Early Miocene, based on Table 1 of Saunders et al. (1986). STRATIGRAPHIC POSITION: Unknown position within formation.

• bed-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

Collection methods: surface (in situ),
