Where: Santa Cruz, Bolivia (17.8° S, 63.2° W: paleocoordinates 19.1° S, 56.7° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Petaca Formation, Oligocene (33.9 - 23.0 Ma)
• This collection had a L. Miocene age assigned. However, the Petaca formation has been considered as an Oligocene-M.Miocene formation. Calle et al., 2018: Therefore, from north to south, available geo-chronologic results indicate an Oligocene– earliest Miocene (∼32–24 Ma) age for the Petaca Formation.
Environment/lithology: terrestrial; lithology not reported
