| Popis: | The new early Sarmatian microvertebrate localities Kozard (Hungary, Nograd County) and Vârciorog (Romania, Bihor County) are of first importance for the understanding of faunal evolution, as well as the palaeoenvironment and palaeoclimate changes during the late middle Miocene in the Central Paratethys. Both localities are rich in Foraminifera and Mollusca. This allows to correlate both continental faunas to the Elphidium reginum foraminifera zone and the Mohrensternia mollusc zone (early Sarmatian s. str.; Serrevalian). Furthermore, Kozard is the type section of the lithostratigraphical unit Kozard Formation. The Cricetodontini are the dominant elements in both rodent faunas which also include, beside smaller cricetid rodents, glirids and sciurids. The large hamster species from Vârciorog is described as new species “Cricetodon” venczeli n. sp. The species from Kozard is a more evolved form, which is very similar to “C.” klariankae from Felsőtarkany-Felnemet 2/3, and thus assigned herein “C.” cf. klariankae. We that these three taxa as belonging to an evolutionary lineage, which underlines their biostratigraphic importance. |
