STRI 130024 (Castilletes Fm) (Miocene to of Colombia)

Also known as Patajau Sur

Where: Guajira, Colombia (11.9° N, 71.3° W: paleocoordinates 11.2° N, 68.2° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Castilletes Formation, Burdigalian to Burdigalian (20.4 - 13.7 Ma)

• Stratigraphic section Patajau Sur (430103) of Moreno et al (2015).

•A mean age of 16.2 Ma (range of 16.33 ± 0.11 Ma–16.07 ± 0.10 month year) is calculated

•for beds in the Patajau Valley near the base of the formation, on the basis of 87Sr/86Sr ratios. Beds in the middle part of the formation near Makaraipao yielded a mean 87Sr/86Sr ratio-derived age of 15.30 Ma (range of 15.14 ± 0.13 Ma–15.43 ± 0.09)

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; sandstone

Size class: macrofossils
