Abstract

The study area, Axamilpa, is located close to the town of Tepexi de Rodríguez in the state of Puebla. The goal of this work is to reconstruct the past environmental conditions through the study of 3 proxies : paleosols, paleobotanical records (stable carbon isotopes and phytoliths) and mammalian fossil remains incorporated in an alluvial paleosol-sedimentary sequence. The AA. interpret the Late Pleistocene landscape of this area as a heterogeneous forest–grassland landscape with the forest shrinking through time and the grass areas increasing. Both isotope and phytolith records demonstrate a contrasting difference between Pleistocene and recent vegetation dominated by xerophytic shrubs and succulents. This vegetation change could play important role in the extinction of Pleistocene megafauna
