| Comments: A new faunal assemblage from cantera Díaz Nogarol, San Luis province (Argentina), is described. Xenarthrans, notoungulates, and rodents of five different families were identified: 1. Dasypodidae: Doellotatus chapalmalensis. Macrochorohates chapalmalensis, Macroeuphractus retusus, Euphractini indet.; 2. Hegetotheriidae: Paedotherium typicum, Paedotherium insigne. Tremacyllus impressus; 3. Octodontidae: Aetenomys sp., Pithanotomys sp., Eucelophorus cf. chapalmalensis sp.; 4. Caviidae: Pascualt'a cf. laeviplicata. Dolicavia minuscula, Caviodon multiplicatus; 5. Chinchillidae: Lagostomopsis sp. The presence of certain taxa such as D. minuscula. P. cf. laeviplicata and C. multiplicatus indicates a Chapadmalalan age for this faunal assemblage within the Late Pliocene. The xenarthran and the pachyrukhine taxa suggest a zoogeographic conexion between the subandean and the pampean regions during that time. The mammal association indicates open habitats, with arid-semiarid paleoenvironmental conditions. | |
