Resumen:
Terrestrial placental carnivores (Mammalia, Carnivora)
of South America are recorded as being in existence since the late Miocene
(Huayquerian), with representatives of the families Felidae, Canidae, Ursidae,
Mustelidae and Procyonidae. The arrival of eutherian carnivores to South
America is closely associated to the rising of the Panamian Isthmus that
permitted the biogeographic event called the "Great American Biotic
Exchange". In this chapter we update the latest advances in the
systematics, phylogeny, biostratigraphy, biogeography and paleoecology of South
American land carnivores. The first records correspond to procyonids dated as
late Miocene (Huayquerian). At the end of the Pliocene (Vorohueian) canids
(Caninae) and mustelids (Mustelinae) appear, but it is at the beginning of the
Ensenadan (late Pliocene ? middle Pleistocene) when the group diversified,
represented by the first record of Ursidae, Felidae, Mephitidae, Lutrinae and
large canids. The diversity of fossil and recent carnivores is a consequence of
several independent immigrations (also within subfamilies and genera), and the
diversification of these immigrants in South America.
