Resumen:
Terrestrial placentary carnivores (Mammalia, Carnivora) of South America are recorded since the late Miocene
(Huayquerian) to the recent, 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 last advances in the systematic, phylogeny, bioestratigraphy, biogeography
and paleoecology of South American land carnivores. The first records
corresponds 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.
