Where: Potosí, Bolivia (21.7° S, 65.6° W: paleocoordinates 22.1° S, 61.9° W)

• coordinate estimated from map

• local area-level geographic resolution

When: Nazareno Formation, Colloncuran (15.5 - 13.8 Ma)

• formation-level stratigraphic resolution

Environment/lithology: fluvial-lacustrine; poorly lithified mudstone and conglomerate
