ABSTRACT
Thanks to the new micromammal fossil material obtained during the 2010 and 2011 field campaigns from the palaeontological site at Húmera (Madrid Basin, central Spain), we have been able to revise the taxonomic arrangement and increase the number of micromammal taxa recorded and described by Menéndez Gamella et al. (2010). During the last campaigns 182 identifiable remains were recovered, in various states of preservation, belonging to 10 different species of micromammals: Megacricetodon collongensisgersii, Democricetodon larteti, Armantomys tricristatus, Microdyromys aff. monspeliensis, Microdyromys koenigswaldi, Heteroxerus rubricati, Heteroxerus grivensis, Heteroxerus sp., Lagopsis sp. and Galerix sp. This fossil association is correlated with biozone E (MN5), and provides new information in relation to the end of the Middle Aragonianfrom the Madrid basin.
