Vaughan et al. loc. 8565 - Rio Yaque del Norte (Oligocene to of Haiti)

Also known as D.C.77B

Where: Haiti (18.7° N, 71.1° W: paleocoordinates 17.8° N, 70.2° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Early/Lower Oligocene to Early/Lower Oligocene (33.9 - 23.0 Ma)

• AGE ASSIGNMENT: Middle Oligocene according to Vaughan et al.. Additionally, the authors state that the assignment of the Oligocene age has more to do with their dissimilarity to overlying Miocene assemblages than similarities with other regional Oligocene faunules (based on forams and corals). I have assigned this an Early to Late Oligocene age, pending more refined biostratigraphic data. STRATIGRAPHIC RELATIONS: no stratigraphic data provided.

• bed-level stratigraphic resolution

Environment/lithology: marine

• ENVIRONMENTAL DATA: no environmental data reported.
• SPECIFIC LITHOLOGY: lithology not reported.

Size class: macrofossils

Collection methods: quarrying,

• COLLECTORS: D.D. Condit (May 21, 1919). REPOSITORIES: unknown repository, possibly Geological Survey of the Dominican Republic, or the USGS/USNM.
