LAS AVES DE LA FAUNA LOCAL PASO DE OTERO (PLEISTOCENO TARDIO) DE LA PROVINCIA DE BUENOS AIRES. SU SIGNIFICACION ECOLOGICA, CLIMATICA y ZOOGEOGRAFICA

EDUARDO PEDRO TONNI, HERMINIO LAZA

Abstract


The vertebrate asse,mblage of this Local Fauna is dominated by mammals, which partially belong to the extinct Pampean megafauna characteristic of the Lujanian Age (Late Pleistocene). These fossils have been collcted from sediments of the Guerrero Member (Luján Formation) exposed on the left bank of the Quequén Grande river at the Paso de Otero, Necochea County. Though bird remains are scarce, the five species recognized so far, provide confirmatory evidence for Tonni and Fidalgo's (1978) palaeoclimatological hypothesis; namely, that most of the Bonarian area was arid and colder than at present during the deposition of the Guerrero Member of the Luján
Formation
