Exceptionally preserved lacustrine ostracods from the Middle Miocene of Antarctica: implications for high-latitude palaeoenvironment at 77 degrees south.

Miocene of Antarctica: implications for high-latitude Exceptionally preserved lacustrine ostracods from the Middle

Mid-Miocene cooling and the extinction of tundra in continental Antarctica.

A major obstacle in understanding the evolution of Cenozoic climate has been the lack of well dated terrestrial evidence from high-latitude, glaciated regions. Here, we report the discovery of exceptionally well preserved fossils of lacustrine and terrestrial organisms from the McMurdo Dry Valleys sector of the Transantarctic Mountains for which we have established a precise radiometric chronol...

The “South Gondwana Fauna” in the Jurassic – an example of the utility of marine Ostracods for palaeobiogeography and palaeogeographic researches

The present article is a review of a palaeobiogeographic analysis of Jurassic Ostracods from East Africa, India and Madagascar and includes also some general remarks on palaeobiogeography, biodiversity and Ostracod ecology.The palaeobiogeographic study shows the high significance of this microfossil group for the reconstruction of palaeogeographic processes, particularly plate tectonic developm...

Quantitative analysis, basin evolution and paleoecology of Early Miocene ostracods in the southwest of Kerman, Iran

This paper focuses on the quantitative analyses of Early Miocene ostracods in south and north of the Sirjan area, southwest of Kerman. Detailed studies resulted in identification of 23 species of ostracoda. The coexisting benthic foraminifera and comparing the identified microfauna assemblages with previous studies confirms the Early Miocene age for the strata. The quantitative analysis show a ...

Sawfishes and Other Elasmobranch Assemblages from the Mio-Pliocene of the South Caribbean (Urumaco Sequence, Northwestern Venezuela).

The Urumaco stratigraphic sequence, western Venezuela, preserves a variety of paleoenvironments that include terrestrial, riverine, lacustrine and marine facies. A wide range of fossil vertebrates associated with these facies supports the hypothesis of an estuary in that geographic area connected with a hydrographic system that flowed from western Amazonia up to the Proto-Caribbean Sea during t...
