We assessed their evolutionary dynamics from the fossil record of Iberian carnivores using per-taxon rates of origination, extinctions and turnover combined with a recent approach for removing the sampling signal from diversity curves. Our analysis interval covers most of the Neogene and the early Pleistocene (MN 2 to MN 17), spanning from around 21.6 to 1.8 Ma. We identified six carnivore associations by applying factor analysis to our data. The diversification pattern shows four origination episodes: MN4, MN7/8, MN12 and MN14. We also identified four extinction episodes. The first two are coincident with the onset of the MN 4 and MN7/8 faunas. The last two extinction episodes take place during MN9, coinciding with the Mid Vallesian Crisis (MVC), and MN13, co-occurring with the Messinian Salinity Crisis (MSC). Two major turnover pulses are recognised during MN4 and MN14, the turnover rate remaining moderately high between MN6 and MN13. We suggest that the pattern observed might be primarily triggered by the biogeographic and climatic shifts that took place during the Neogene.

De acuerdo a esta reglamentación, las labores mineras realizadas en el Cerro de los Batallones (Torrejón de Velasco, Madrid), área en la que se encuentra el excepcional yacimiento de vertebrados miocenos de Batallones-1, han sido sistemáticamente controladas para prevenir la destrucción de nuevos yacimientos paleontológicos. Como consecuencia de estas actuaciones han sido localizadas cuatro nuevas localidades con vertebrados fósiles. Palabras clave: Patrimonio Paleontológico, explotación minera, actuaciones de protección, Cerro de los Batallones, Madrid.

An updated biochronological arrangement of the Madrid basin faunas is proposed based on the results of similarity analyses. Similarity analysis was performed using either entire faunas, the large mammals, or the small mammals and the results are discussed and compared with other biochronologic and biostratigraphic European scales. New data on the relative abundance of mammal taxa from localities of the Madrid basin are presented and discussed.
