Where: Oruro, Bolivia (18.1° S, 67.9° W: paleocoordinates 18.3° S, 66.0° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Rosa Pata Formation, Late/Upper Miocene (11.6 - 5.3 Ma)

• The material of S. uccasamamensis was found 15 m below ‘Toba 76’ from the Rosa Pata Formation (late Miocene) unconformably overlain by the Umala Formation (Pliocene; Saint-André et al., 2010).

•This specimen is considered to represent the oldest known remains of S. uccasamamensis, im- mediately before the Huayquerian–Montehermosan transition and most probably predating the Miocene– Pliocene transition.

•

•a horizon bounded below by Toba 76 and above by another volcanic level, the 2.8 Ma Ayo Ayo tuff ; its age is Montehermosan- Chapadmalalan (early and middle Pliocene)

• group of beds-level stratigraphic resolution

Environment/lithology: terrestrial; red sandstone

Size classes: macrofossils, mesofossils

Preservation: permineralized

Collected by P.-A. Saint-André, F. Pujos in 1989-1990, 2000

• P.-A. Saint-André collected specimens in 1989-1990 and published them in his thesis in 1994 and F. Pujos revisited some of the same localities in 2000 for his thesis. Results are presented in this paper.
