Paleogene, Maastrichtian, and Miocene floras are reviewed. They are located on continental margins, where several sedimentary basins developed. The affinities of the fossil genera to living ones allow the recognition of three paleofloras: Neotropical, Mixed, and Antarctic. These could be the forerunners, respectively, of the presently more humid dominions in Neotropical Region (Caribbean, Amazonic, and Guayano), of the drier ones (Chaquefto and Andino-Patagonico), and ofthe Subantarctic… 
Quantitative Analysis of Cenozoic Palynofloras from Patagonia, Southern South America
The statistical analysis of published Paleocene-Late Miocene palynological data from Patagonia supports several major stages of vegetation. These stages represent distinctive floral assemblages, both
Splendid and Seldom Isolated: The Paleobiogeography of Patagonia
The idea that South America was an island continent over most of the Cenozoic, during which its unusual mammalian faunas evolved in isolation, is outstandingly influential in biogeography. Although
Cretaceous Paleobotany and Its Bearing on the Biogeography of Austral Angiosperms
Plant fossils from Antarctica have played a major role in developing concepts of the geological history of the Southern Hemisphere. Disjunct austral distributions of extant taxa (e.g., Hooker 1853)
Paleoenvironmental evolution of southern South America during the Cenozoic
Southern South America (SSA) has today a high diversity of climates, environments, biomes, and biotas, as a result of the complex interaction through time of plants and animals with the geological
Paleobiogeographic relationships of Andean angiosperms of Cretaceous to Pliocene age
Abstract A review of the geological data suggests that mountains existed in western South America since the late Cretaceous. These data combined with a review of the earliest occurrences of
Abstract. A moderately diverse terrestrial biota is known from the Eocene - ?early Oligocene La Meseta Formation, Seymour Island, Antarctic Peninsula. The La Meseta Formation fills an incised valley
Cainozoic ferns and their distribution
The phytogeographic distribution of Cainozoic ferns is reported based upon a critical re-appraisal of the macrofossil and mesofossil record also taking account of evidence from a few highly
On the persistence of Tropical Paleofloras in central Chile during the Early Eocene
Abstract Mixed paleofloras first appeared during the Early Eocene of southern South America. These floras were a blend of cold and warm taxa with Austral-Antarctic and Neotropical affinities. Despite
The evolution of Patagonian climate and vegetation from the Mesozoic to the present
In this review, Patagonian phytogeographical patterns are analysed from a global and evolutionary perspective that takes into account aspects from the geology, climatology and plant evolution. The
Paleogene imbricate-leaved podocarps from King George Island (Antarctica): assessing the geological context and botanical affinities
Imbricate-leaved podocarps (Dacrydium s.l.) are the dominant conifer remains in the Upper Cretaceous and Cenozoic successions of King George Island, increasing its abundance in the post-Late
