Flora fóssil dos níveis de bentonita da formação Campos Novos (Oligoceno Superior) Bacia de Boa Vista, PB, Brasil
(Universidade do Vale do Rio dos Sinos, 2015-03-02)
The end of Oligocene was a critical time for angiosperm evolution, with the definitive establishment of modern vegetation and grass-dominated landscapes. Is was also a time marked by important geological events, with the ...

Alternative interpretations of some earliest ediacaran fossils from China
(2013-03-01)
In a letter to Nature (February, 2011), Xunlai Yuan and collaborators recorded carbon compression fossils from black shales of the Lantian Formation (Ediacaran), southern Anhui Province, South China. The new fossils, ...

Fossil woods from the Eocene of Corcovado, Argentinean Patagonia: geological setting and conifer diversity
(International Association of Wood Anatomists, 2021-05)
Eocene paleofloras of Patagonia are diverse and increasingly known. A new assemblage of fossil wood has been recovered from Eocene sediments in Corcovado, western Argentinean Patagonia. The lithological succession (formerly ...
Early Miocene CO2 estimates from a Neotropical fossil leaf assemblage exceed 400 ppm
(Wiley-Blackwell Publishing Ltd, 2018-11-01)
Premise of the Study: The global climate during the early Miocene was warmer than the present and preceded the even warmer middle Miocene climatic optimum. The paleo-CO2 records for this interval suggest paradoxically low ...
The micro-and megafossil record of Nothofagaceae from South America
(Wiley Blackwell Publishing, Inc, 2020-12)
We compiled the numerous fossil records (486) assigned to Nothofagaceae including pollen grains (from surface sediments and continental and oceanic borehole cores), leaves, woods and reproductive structures from South ...
Last glacial maximum environments in northwestern Patagonia revealed by fossil small mammals
(Academic Press Inc Elsevier Science, 2014-05-26)
Comparisons of historical and modern assemblages of mammals can yield important insights into patterns and processes of environmental change. Here, we present the first analyses of small mammal assemblages present in ...
Palaeoecological analysis of two Late Pleistocene continental mollusc assemblages from Uruguay
(Zoologische Staatssammlung München, 2022)
Extant continental (freshwater and terrestrial) molluscs are very informative from an environmental point of view. The specific environmental requirements of different taxa can be extrapolated to the fossil assemblages in ...
