STRI Loc. 290820 - Near Huaina [middle Jimol Fm] (Miocene of Colombia)

Where: La Guajira, Colombia (12.0° N, 71.3° W: paleocoordinates 11.2° N, 68.0° W)

• coordinate based on unpublished field data

• small collection-level geographic resolution

When: middle 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 unconformably 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 117 m below the Jimol/Castilletes contact.

• bed-level stratigraphic resolution

Environment/lithology: coastal; unlithified siltstone

• ENVIRONMENT: Shallow marine (10-50 m), siliciclastic.
• SPECIFIC LITHOLOGY: Unconsolidated 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 2014

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

• COLLECTOR: A. Hendy, 01/20/2014. REPOSITORY: Presently reposited at FLMNH, Gainesville.
