Woodring Loc. 99d - Canal Zone [lower Culebra Fm] (Miocene of Panama)

Also known as USGS Loc. 6019d

Where: Panama (9.1° N, 79.7° W: paleocoordinates 8.1° 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: marine; poorly lithified, fine-grained shale and carbonaceous mudstone

• No paleoenvironmental data reported.
• Collection assumed to be from lower part of formation. The lower part of the formation comprises: dark-colored, thin-bedded or laminated, fine-grained rocks; carbonaceous or lignitic shale, carbonaceous silty mudstone, tuffaceous siltstone. The upper part comprises: calcareous and sandy strata, and ranges from tuffaceous amd pebbly calcareous sandstone to sandy limestone.

Size class: macrofossils

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).
