Also known as STRI Sample 38145; AH140154
Where: La Guajira, Colombia (11.9° N, 71.3° W: paleocoordinates 11.3° N, 68.6° W)
• coordinate based on unpublished field data
• small collection-level geographic resolution
When: middle Castilletes Member (Castilletes Formation), Langhian (16.0 - 13.8 Ma)
• STRATIGRAPHIC RELATIONS: From the Castilletes Formation, which conformably overlies the Jimol Formation (early Miocene) and is unconformably overlain by the Ware Formation. AGE: Langhian, on the basis of macrofaunal composition; direct age established by extrapolation of Sr-isotope dating by enterer. STRATIGRAPHIC POSITION: From middle member of Castilletes Fm. Sampled from the lower of two coquinas, separated by 2 m of non-marine mudstone; from 193 m above Jimol/Castilletes contact.
• bed-level stratigraphic resolution
Environment/lithology: lagoonal; poorly lithified, shelly/skeletal siltstone
Size classes: macrofossils, mesofossils
Preservation: original aragonite, original calcite
