Duke Locality 121 W (La Venta Fauna) (Miocene of Colombia)

Where: Colombia (3.3° N, 75.1° W: paleocoordinates 2.7° N, 72.3° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Honda Group, Middle Miocene (16.0 - 11.6 Ma)

• The map doesn't show 121 W, but 121 is near Duke Locality 117 in the La Victoria Formation.

•Note: this collection had a Friasian age attached but here must be the Friasian sensu lato, that includes the Friasian sensu stricto, Mayoan and Laventan. We don't have any indication of a formation for this collection. So the age is corrected to M. Miocene.

• formation-level stratigraphic resolution

Environment/lithology: terrestrial; lithology not reported

Size class: macrofossils
