UCMP Locality V4521 (La Venta Fauna) (Miocene of Colombia)

Where: Huila Department, Colombia (3.2° N, 75.2° W: paleocoordinates 2.6° N, 72.6° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Baraya Member (Villavieja Formation), Laventan (13.8 - 11.0 Ma)

•Note: this collection was noted as Miocene age. But Flynn et al., 1997 dated the Honda group and found that the monkey beds belong to the Villavieja formation, Baraya member and have an age of apr. 12.5Ma. This makes them of Laventan age.

• group of beds-level stratigraphic resolution

Environment/lithology: terrestrial; lithology not reported

Size class: macrofossils
