The rich and relatively diverse fossil mammalian assemblage from Gokler is of special importance for understanding of faunal evolution in Central Anatolia. Large mammals were not recovered, but insectivores and rodents are abundant. The assemblage of rodents is studied in detail and comprises mainly diversified cricetids. Dormice are abundant, but are represented by only one species. Squirrels are represented only by few specimens and also beaver remains were identified. Spanocricetodon sinuosus is referred to a new genus Latocricetodon nov. gen that is tentatively assigned to the Pseudocricetodontinae. Newly named species are Cricetodon goklerensis sp. nov., Democricetodon haltmari sp. nov., Eumyarion lukasi sp. nov. and Glirudinus matusi sp. nov. The rodent assemblage is assigned to local zone C which is correlated to the European biounit MN2 (early Miocene). Our biochronological assessment is supported by radiometric dating from two volcanic ash layers.
