Also known as Woodring Loc. 99b

Where: Panama (9.1° N, 79.7° W: paleocoordinates 8.1° N, 77.3° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: 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: marine; poorly lithified, fine-grained shale and carbonaceous mudstone

Size class: macrofossils

Collected by D.F. MacDonald, T.W. Vaughan in 1911; reposited in the USNM

Collection methods: quarrying,

• Collected by MacDonald and Vaughan (1911). 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).
