Duke Locality 46 (La Venta Fauna) (Miocene of Colombia)

Where: Colombia (3.3° N, 75.2° W)

• Paleocoordinates: 4.0° N, 71.6° W (Wright 2013)

• 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: lacustrine - large; green claystone and green mudstone

• "appears to be a lake or swamp deposit ...at least 10 km in diameter"
• "This green claystone and mudstone is characerized by enormous quantities of disarticulated fish remains"

Size class: macrofossils

Collection methods: a partial caudal ring
