STRI Loc. 290804 (Quadrat C) - Kabarauremana [upper 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• coordinate based on unpublished field data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: 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 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 and stratigraphic position. STRATIGRAPHIC POSITION: From uppermost part of the Jimol Formation; from 64 m below Jimol/Castilletes contact.

• bed-level stratigraphic resolution

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

• ENVIRONMENT: Not fully marine, siliciclastic, very shallow.
• 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

Collected by Hendy in 2014

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

• COLLECTOR: A. Hendy, 01/19/2014. REPOSITORY: Presently reposited at Uni. Norte, Colombia. ABUNDANCE: Estimate based on relative abundance within a 25cm2 quadrat; A=abundant (10 or more specimens per quadrat; C=common (3-9 specimens per quadrat; R=rare (1-2 specimens per quadrate).
