Geography
Country:Colombia State/province:La Guajira
Coordinates: 11.9° North, 71.4° West (view map)
Paleocoordinates:11.2° North, 68.2° West
Basis of coordinate:unpublished field data
Geographic resolution:small collection
Time
Period:Neogene Epoch:Miocene
10 m.y. bin:Cenozoic 5
Key time interval:Burdigalian - Langhian
Age range of interval:20.44000 - 13.82000 m.y. ago
Stratigraphy
Formation:Castilletes Member:lower Castilletes
Regional section:Cocinetas Regional bed:49 m
Regional order:bottom to top
Stratigraphic resolution:bed
Stratigraphy comments: 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.

Includes fossils?Y
Lithology description: SPECIFIC LITHOLOGY: Unconsolidated shell bed, silty matrix. LITHIFICATION: Unlithified, as determined in the field and based on museum-reposited specimens.

Geology comments: ENVIRONMENT: Shallow marine (0-5 m), siliciclastic, probably reduced salinity.
