Duke Locality 32 (La Venta Fauna) (Miocene of Colombia)

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

• coordinate estimated from map

• local area-level geographic resolution

When: Cerro Colorado Member (Villavieja Formation), Laventan (13.8 - 11.8 Ma)

• Note: This collection had a Friasian age but this must be the Friasian sensu lato, that includes the Friasian sensu stricto, Mayoan and Laventan.

•The Cardon Red beds have been dated as 12.2-12.5Ma aprox. (Flynn et al., 1997). this makes them Laventan in 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: fluvial; red, silty claystone and mudstone

• Channel and overbank deposits
• Fine-grained deposits, including red claystone and mudstone with very minor sandstone

Size class: macrofossils
