Cricetidae (Rodentia, Mammalia) from the upper Oligocene of Mirambueno and Vivel del Rio (prov. Teruel, Spain)

The Cricetidae from a number of Oligocene mammal-bearing localities near Montalbán (prov. Teruel, Spain) are described. The cricetid fauna is characterised by the dominance, both in number of species and in number of specimens, of the subfamily Pseudocricetodontinae. A local faunal zonation on the basis of Cricetidae is given. Two new species are described: Eucricetodon martinensis sp. nov., and Allocricetodon cornelii gen. nov., sp. nov.
