Resumen:
Cenozoic South American Land MammalAges (SALMAs) have historically beencorrelated to the geologic time scale using40Ar/39Ar dating and magnetostratigraphy.At Gran Barranca (68.7°W, 45.7°S)?one ofSouth America?s key areas for constrainingSALMAs?existing radioisotopic ages haveuncertainties of up to 4 m.y. To better constrainthe ages of mammalian assemblages,we employed high-precision (±
