Geography
Country:Colombia State/province:La Guajira
Coordinates: 11.9° North, 71.4° West (view map)
Paleocoordinates:11.1° North, 68.1° West
Basis of coordinate:unpublished field data
Geographic resolution:small collection
Time
Period:Neogene Epoch:Miocene
Stage:Burdigalian 10 m.y. bin:Cenozoic 5
Key time interval:Burdigalian
Age range of interval:20.44000 - 15.98000 m.y. ago
Stratigraphy
Formation:Jimol Member:middle Jimol
Regional section:Cocinetas Regional bed:-113 m
Regional order:bottom to top
Stratigraphic resolution:bed
Stratigraphy comments: 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: Probably from the middle section of Jimol Formation, but uncertain as from a faulted area; from 113 m below the Jimol/Castilletes contact.
