STRI Loc. 290430 - ParĂ¡uachon [upper Jimol Fm] (Miocene of Colombia)

Also known as STRI Sample 17068, 17071, 17090, 38475

Where: La Guajira, Colombia (11.9° N, 71.4° W: paleocoordinates 11.2° N, 68.1° W)

• coordinate based on unpublished field data

• small collection-level geographic resolution

When: upper Jimol Member (Jimol Formation), Burdigalian (20.4 - 16.0 Ma)

• STRATIGRAPHIC RELATIONS: From the Jimol Formation, which conformably overlies the Uipta Formation (early Miocene) and is conformably overlain by the Castilletes Formation. This area and nearby collections have been previously mapped as Castilletes Formaton (late Pliocene-early Pleistocene). AGE: Burdigalian, on the basis of macrofaunal composition; direct age established by extrapolation of Sr-isotope dating by enterer. STRATIGRAPHIC POSITION: From the upper section of Jimol Formation; same horizon as STRI Loc. 290376; from 42 m below Jimol/Castilletes contact.

• bed-level stratigraphic resolution

Environment/lithology: lagoonal; unlithified, shelly/skeletal siltstone

• ENVIRONMENT: Siliciclastic, shallow subtidal (0-30 m).
• SPECIFIC LITHOLOGY: Unconsolidated shell bed, silty matrix. LITHIFICATION: Unlithified, as determined in the field and based on museum-reposited specimens.

Size classes: macrofossils, mesofossils

Preservation: original aragonite, original calcite

Collected by Hendy in 2011

Collection methods: surface (float), surface (in situ),
