Bulla Rver, River Mao (Miocene of Dominican Republic)

Where: Dominican Republic (19.4° N, 71.1° W: paleocoordinates 19.4° N, 70.3° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Cercado Formation, Late/Upper Miocene (11.6 - 5.3 Ma)

• No paleoenvironmental data reported by Maury.
• No lithologic data reported.

Size class: macrofossils

Preservation: original aragonite
