Stratigraphy
| Formation: | Quehua | ||||
| Stratigraphic resolution: | formation | ||||
| Stratigraphy comments: 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). | |||||
