Sensitivity of leaf size and shape to climate: global patterns and paleoclimatic applications.
It is demonstrated that the inclusion of additional leaf traits that are functionally linked to climate improves paleoclimate reconstructions and illustrates the need for better understanding of the impact of phylogeny and leaf habit on leaf-climate relationships. Expand
A Paleocene lowland macroflora from Patagonia reveals significantly greater richness than North American analogs
Few South American macrofloras of Paleocene age are known, and this limits our knowledge of diversity and composition between the end-Cretaceous event and the Eocene appearance of high floralExpand
Paleogene Land Mammal Faunas of South America; a Response to Global Climatic Changes and Indigenous Floral Diversity
In addition to being composed of essentially different groups of mammals, those of the South American continent seem to have responded to the climatic changes associated with the ECCO and subsequent conditions in a pattern that was initially comparable to, but subsequently different from, their North American counterparts.

Fossil evidence for Cretaceous escalation in angiosperm leaf vein evolution
Using vein density (DV) measurements of fossil angiosperm leaves, it is shown that the leaf hydraulic capacities of angiosperms escalated several-fold during the Cretaceous, providing fossil evidence for the hypothesis that significant ecosystem change brought about by angios perms lagged behind the Early Cret Jurassic taxonomic diversification ofAngiosperm.

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. TheExpand
New Age Constraints for the Salamanca Formation and Lower Río Chico Group in the Western San Jorge Basin, Patagonia, Argentina: Implications for Cretaceous-Paleogene Extinction Recovery and Land
The Salamanca Formation of the San Jorge Basin (Patagonia, Argentina) preserves critical records of Southern Hemisphere Paleocene biotas, but its age remains poorly resolved, with estimates rangingExpand
Papuacedrus (Cupressaceae) in Eocene Patagonia: A new fossil link to Australasian rainforests.
Combined evidence indicates a biome similar to extant subtropical, or tropical montane, rainforests that persisted for at least 4.4 Myr, linking elevated floral richness to abundant rainfall. Expand
The Gibraltar Strait: A Pleistocene door of Europe?
The possibility thatHomo crossed the Gibraltar Strait during the Plio-Pleistocene is currently debated. The finds of human remains and lithic artefacts in different Plio-Pleistocene beds of the OrceExpand
