Also known as USGS Loc. 5860

Where: Panama (9.0° N, 79.6° W: paleocoordinates 8.0° N, 77.3° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: lower Member (Culebra Formation), Aquitanian (23.0 - 20.4 Ma)

• LITHOSTRATIGRAPHY: From the Culebra Formation, which unconformably overlies the Las Cascadas agglomerate; reassigned to La Boca Fm in subsequent publications of Woodring (e.g., 1973, 1982), but further emended by Kirby et al. (2009) to the lower member of the Culebra Formation. AGE: Early Miocene in text; direct date extrapolated from Kirby et al. (1999), =Aquitanian.

• bed-level stratigraphic resolution

Environment/lithology: coastal; poorly lithified, pebbly, tuffaceous, calcareous sandstone and sandy limestone

Size class: macrofossils

Reposited in the USNM

Collection methods: quarrying,

• Collected by MacDonald (1913). Material is also held (but not specified for any specific collection) at Stanford University, Acad. Nat. Sci. Phil., Corenell University, PRI, U. Cal. and Cal. Acad. Sci. Locality now unaccessible (submerged).
