Resumen:
We summarize the geotectonic history of the southern (mostly Patagonian) Andean Cordillera, and its possible
influence on the regional expression of global climates, biogeography, and important aspects of mammalian
evolution in South America. The northern Patagonian segment of the Andes contrasts with neighbouring sections
in that, during Palaeogene times, there was a transform margin stage; this influenced the Andean climate in
addition to global climate changes. This segment underwent alternating subduction and transform episodes that
suggest the existence of a proto-Andes and an Oligocene Andean gap for the San Carlos de Bariloche area. Coeval
with this gap (and at the backarc region of this segment), the 12001500 m uplift of the Northern Patagonian
Massif took place, resulting in an altiplano (high plateau), or Northern Patagonian High Plateau (NPHP), of
100 000 km2, which dominated northern Patagonia during the Oligocene. It is estimated that, by these times,
climate in the NPHP was humid and seasonally cool, in contrast to the seasonally more uniform, humid climates
of the lower lands peripheral to it. The NPHP may have acted as a biogeographical barrier between central and
southern Patagonia, on one side (as part of the Austral Biogeographical Kingdom), and the rest of South America
(Holotropical Kingdom) on the other. The most important Paleogene mammalian turnover transpired at the Early
Oligocene, concomitantly with the full opening of the Drake Passage and associated global cooling. The latitudinal
climate gradient that began at the EoceneOligocene transition affected sharply the entire Patagonian region, an
effect that was enhanced by the uplift of the NPHP. © 2011 The Linnean Society of London, Biological Journal
