Ayo Ayo-Viscachani (Neogene of Bolivia)

Where: La Paz, Bolivia (17.1° S, 68.0° W: paleocoordinates 17.2° S, 66.8° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Umala Formation, Montehermosan (6.8 - 4.0 Ma)

• Ages obtained by Marshall et al. (1992).

•Overall, the remains of S. uccasamamensis are from deposits that are virtually bracketed below by ‘Toba 76’, which we consider now dated at 5.26 ± 0.02 Myr, and above by the 2.8 Myr Ayo Ayo tuff, which correspond to the base and the top of the Umala Formation and roughly coincide with the Pliocene (Marshall & Sempéré, 1991)

• group of beds-level stratigraphic resolution

Environment/lithology: lacustrine - large; lithified, sandy sandstone

Size classes: macrofossils, mesofossils

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

• Repository: Museo Nacional de Historia Natural La Paz

•Saint Andre et al 2010: 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.
