STRI Loc. 290423 [bulk#2] - Paráguachon [lower Castilletes Fm] (Miocene to of Colombia)

Also known as STRI Sample 16855

Where: La Guajira, Colombia (11.9° N, 71.4° W: paleocoordinates 11.2° N, 68.2° W)

• coordinate based on unpublished field data

• small collection-level geographic resolution

When: lower Castilletes Member (Castilletes Formation), Burdigalian to Burdigalian (20.4 - 13.8 Ma)

• STRATIGRAPHIC RELATIONS: From the Castilletes Formation, which conformably overlies the Jimol Formation (early Miocene) and is unconformably overlain by the Ware Formation. AGE: Burdigalian-Langhian, on the basis of macrofaunal composition and stratigraphic position; direct age established by extrapolation of Sr-isotope dating by enterer. STRATIGRAPHIC POSITION: Likely in lower part of the Castilletes Fm, but in a faulted part of the sequence; from 49 m above Jimol/Castilletes contact.

• bed-level stratigraphic resolution

Environment/lithology: lagoonal; poorly lithified, gypsiferous, shelly/skeletal siltstone

• ENVIRONMENT: Shallow marine (0-5 m), siliciclastic, probably reduced salinity.
• SPECIFIC LITHOLOGY: Poorly consolidated shell bed, silty matrix, gypsiferous. LITHIFICATION: Poorly lithified, as determined in the field and based on museum-reposited specimens.

Size classes: macrofossils, mesofossils

Preservation: original aragonite, original calcite
