Duke Locality 6 (La Venta Fauna) (Miocene of Colombia)

Where: Colombia (3.3° N, 75.2° W: paleocoordinates 2.7° N, 72.6° W)

• coordinate estimated from map

• local area-level geographic resolution

When: Baraya Member (Villavieja Formation), Laventan (13.8 - 11.0 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 lower Villavieja formation (Baraya member) is considered of Laventan age now and the upper Villavieja formation is considered Laventan-Mayoan in age (Flynn et al., 1997).

• group of beds-level stratigraphic resolution

Environment/lithology: fluvial; gray, green mudstone and gray, green sandstone

• "14.8 m of extremely fossiliferous greenish-gray mudstone and sandstone....fining upward sequence is 1-m-thick medium-grained sandstone followed by 4.5 m of reddish-brown sandy mudstone, 1.2 m of pale-green mudstone, and on top, 0.8 m of reddish-brown mudstone"

Size class: macrofossils

Collection methods: One scute and miscellaneous postcranial bones
