Resum

The middle Miocene global cooling event has been described at a local scale in central Spain (Madrid Basin). There are well-studied fossil sites as Somosaguas (14.1 Ma) and Cerro de los Batallones (9 Ma). In addition, other fossil sites situated temporarily between them, such as the Paracuellos del Jarama fossil sites have a great potential. In this work, the palaeoenvironments of Paracuellos-5(13.7 Ma) and Paracuellos-3 (12.8 Ma) sites, both from the middle Miocene, have been characterized to show a more complete view of the environmental characteristics prevailing during this period. Six quantitative climatic inference models based on body-size structure of mammal faunas have been used to estimate temperature and precipitation of the study area. The obtained environmental inferences allow formulating the hypothesis that, in a time interval of less than 1 million years, the environment of Paracuellos experienced a trend through slightly more humid conditions, remaining as an extremely arid environment.
