Vertebrates from the Middle Pleistocene locality Lysa Gora 1 in Ukraine.

Abstract: A vertebrate fauna from the new Middle Pleistocene locality Lysa Gora 1 of Southern Ukraine (Zaporizhya region) is described. The locality has yielded an assemblage of at least 11 taxa of bony fishes (Cypriniformes, Siluriformes, Esociformes, Perciformes) and small mammals (Lagomorpha – 2 taxa, Rodentia – 11 species). The species composition of Arvicolidae, particularly the presence of Lagurus transiens, Eolagurus luteus, Arvicola mosbachensis, Microtus (Terricola) arvalidens, and Microtus (Stenocranius) gregalis, as well as the structure of the fauna, suggests Middle Pleistocene age (MQR 4, MIS 13-12, Early Toringian). New data on the paleoecology of the locality and taxonomy/phylogeny of selected taxa are discussed. [Copyright &y& Elsevier]
