New Chinchillid Rodents (Hystricognathi: Caviomorpha) from Northern Chile and Bolivia Fill a 17-Million-Year Gap in the Pan-Chinchilline Fossil Record
The fossil record of chinchillid rodents (Hystricomorpha: Caviomorpha) begins in the early Miocene. However, nearly all remains have thus far been limited to the Lagostominae, which includes the extant plains ...

Middle Jurassic-Late Cretaceous Paleogeography of the Western Margin of the Neuquén Basin (34° 30′–36° S)
U–Pb dating of detrital and igneous zircons from the retroarc deposits of the Neuquén Basin has shed light over the Mesozoic evolution of the western border of South America, yet the coeval arc and forearc reg...

The Pre-Andean Phases of Construction of the Southern Andes Basement in Neoproterozoic–Paleozoic Times
During the late Neoproterozoic and Paleozoic times, the southern Andes of Argentina and Chile (21º–55º S) formed part of the southwestern margin of Gondwana. During this period of time, a set of continental fr...

Cenozoic tectonic evolution in the Central Andes in northern Chile and west central Bolivia: implications for paleogeographic, magmatic and mountain building evolution
A review of available stratigraphic, structural, and magmatic evolution in northernmost Chile, and adjacent Peru and Bolivia shows that in this region: (1) compression on the Paleogene intra-arc during the mid...

An Early Miocene anthropoid skull from the Chilean Andes
PARTLY because of their poor fossil record, the relationships of neotropical platyrrhine monkeys to other groups of primates and to each other remain perhaps the most poorly known for any major primate clade1. He...

Jurassic Cretaceous Palaeogeographic Evolution of the Chilean Andes at 23°–24°S Latitude and 34°–35°S Latitude: A Comparative Analysis
A comparative palaeogeographic analysis between the northern (23°–24°S) and central (34°–35°S) Chilean Andes during the Jurassic and the Cretaceous indicates that both regions had the following general palaeog...

South America's earliest rodent and recognition of a new interval of mammalian evolution
THE mid-Cenozoic immigration of rodents and primates to South America (when it was widely isolated by oceans) represents a pre-eminent problem in the biogeographical history of placental mammals. The unexpecte...
