A Late Miocene Argyrolagidae (Mammalia, Metatheria, Bonapartheriiformes) from Northwestern Argentina
The new record reported here, the third known of Microtragulus from northwestern Argentina, broadens the geographic range of the genus, known from the Atlantic coast of Argentina and several localities of the Andean highlands and the foothills of the cordilleran range.
Neotropical mammal diversity and the Great American Biotic Interchange: spatial and temporal variation in South America's fossil record
This study investigates biogeographic patterns in South America, just before or when the first immigrants are recorded and reviews the temporal and geographical distribution of fossil mammals during the GABI, and performs a dissimilarity analysis which grouped the faunal assemblages according to their age and their geographic distribution.
New records of Neogene Xenarthra (Mammalia) from eastern Puna (Argentina): diversity and biochronology
Abstract. Xenarthra is an endemic South American lineage of mammals, probably the sister clade of the other placental mammals. The oldest records of Xenarthra are from the latest Paleocene, although
Mammals from the Salicas Formation (Late Miocene), la Rioja Province, Northwestern Argentina: Paleobiogeography, Age, and Paleoenvironment
Abstract. This study analyzes a collection of fossil mammals from the Salicas Formation in the El Degolladito area, La Rioja Province, Argentina. The materials reported herein were recovered from
Strangers in a strange land: Ecological dissimilarity to metatherian carnivores may partly explain early colonization of South America by Cyonasua-group procyonids
Abstract. It was once thought that the endemic carnivorous mammals of South America, the metatherian sparassodonts, were driven extinct by North American carnivorans through competitive exclusion.
Neogene sloth assemblages (Mammalia, Pilosa) of the Cocinetas Basin (La Guajira, Colombia): implications for the Great American Biotic Interchange
We describe sloth assemblages from the Cocinetas Basin (La Guajira peninsula, Colombia), found in the Neogene Castilletes and Ware formations, located in northernmost South America, documenting
Continental Relationships, Chronostratigraphy, Climates, and Mammalian Biogeography of Southern South America Since Late Miocene
The biotic interchange between the Americas occurred in several phases during more than nine million years. In this book, we focus on mammals of southern South America, where the most important and
Carnivorans at the Great American Biotic Interchange: new discoveries from the northern neotropics
The phylogenetic analysis that includes the two new findings support the view that procyonids dispersed from North America in two separate events, which involved reciprocal lineage migrations from North to South America, and included the evolution of South American endemic forms.
First Record of Carnivora (Puma Lineage, Felidae) in the Uquía Formation (Late Pliocene–Early Pleistocene, NW Argentina) and Its Significance in the Great American Biotic Interchange
Abstract. The fossil record of the puma lineage in America is sparse, and doubts have been raised about the origin, radiation, and migration events of this lineage. In this study, we present results


Chronostratigraphy and “Land-Mammal Ages” in the Cenozoic of southern South America: principles, practices, and the “Uquian” problem
The concept of “land-mammal age” as developed in South America is examined. The “Uquian Land-mammal age” is used as a study case. “Land-mammal age” parataxonomy is here considered methodologically
A revised Cenozoic geochronology and chronostratigraphy
Since the publication of our previous time scale (Berggren and others, 1985c = BKFV85) a large amount of new magneto- and biostratigraphic data and radioisotopic ages have become available. An
