UCMP Locality V4524 (La Venta Fauna) (Miocene of Colombia)

Also known as V-4524

Where: Huila, 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)

• collected from the unit above the Fish Bed

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

•The Honda Group is constrained by radiometric and paleomagnetic evidence to between approximately 13.5 Ma–11.8 Ma (Flynn et al., 1996; Guerrero, 1996; Madden et al., 1996).

• group of beds-level stratigraphic resolution

Environment/lithology: terrestrial; claystone and sandstone

• clay and sandstone lentils

Size class: macrofossils

Collected by Fields in 1959; reposited in the UCMP
