Abstract


THE OLDEST RECORD (EARLY-MIDDLE PLEISTOCENE) OF AKODON AZARAE (FlSCHER, 1829) (MAMMALlA, RODENTlA, CRICETIDAE) AT BUENOS AIRES PROVINCE, ARGENTINA. The oldest record of Akodon azarae from early-middle Pleistocene sediments at Buenos Aires province is described. An incomplete skull of this species was found in "La Delicia" beach (General Pueyrredón county), associated with remains of Mesotherium cristatum (fossil characteristic to the Ensenadean South American Land Mammal age). This new remains led to enhance the known range of A. azarae in the Quaternary of Buenos Aires province: early/middle Pleistocene-Holocene. Some considerations on zoogeographic and palaeoecology aspects are made.
