In this paper, the insectivores, chiropterans and rodents from the middle Miocene site of Can Missert are described. The faunal list of this locality includes the following species: Miosorex grivensis, Desmanella sp., Talpidae indet., Vespertilionidae indet., Hispanomys daamsi, Megacricetodon minor, Megacricetodon ibericus, Fahlbuschia crusafonti, Democricetodon brevis nemoralis, Eumyarion medium, Muscardinus hispanicus, Eomuscardinus sp., Paraglirulus werenfelsi and Spermophilinus bredai. H. daamsi is a new Cricetodontine species which is characterized by complete ectolophs and relatively long third lower molars. The rodent association of Can Missert enable one to assign this locality to the late Aragonian, MN 8, being close in age to other localities in the Vallès-Penedès Basin such as Castell de Barberà. However, the proportion in which each species is represented is very different in the two cases. This evidence points to the existence climatic pulses at the end of the Aragonian Mammal-Stage.
