Where: Potosí, Bolivia (20.0° S, 67.0° W: paleocoordinates 20.6° S, 62.9° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Quehua Formation, Burdigalian to Burdigalian (20.4 - 13.8 Ma)
• This collection had a M. to L. Miocene age. However, a paleomagnetic section with associated radioisotopic dates constrains the fossiliferous horizons to ca. 16.5–15.3 Ma (late early to early middle Miocene) (MacFadden et al., 1995).
• formation-level stratigraphic resolution
Environment/lithology: terrestrial; lithology not reported
Size classes: macrofossils, mesofossils
