Also known as USGS Loc. 6443
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, calcareous sandstone
Size class: macrofossils
Reposited in the USNM
Collection methods: quarrying,
• Collected by Arnold and 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).
