The Aragonian and Vallesian high-resolution micromammal succession from the Calatayud-Montalbán Basin (Aragón, Spain)

Abstract

We present an updated taxonomy and faunal distribution of the micromammal fossil record from the Aragonian and lower Vallesian of the Calatayud-Montalbán Basin. The analysed record includes the orders Rodentia, Eulipotyphla, and Lagomorpha. The pattern of species turnover showsseven major faunal events,which are correlated to major climate changes based on marine stable oxygen and carbon isotope records. The episodesδ 18OMi-2 and Mi-3 are significantly correlated with major micromammal turnover at the boundaries between lower and middle Aragonian and middle and upper Aragonian, respectively. Our resultssupport the existence of a selective turnover during the Aragonian and lower Vallesian
