A new record of late Ediacaran acritarchs from La providencia group (Tandilia System, Argentina) and its biostratigraphical significance
(Elsevier B.V., 2019-08-01)
A well preserved assemblage of organic-walled microfossils is described from the Alicia and Cerro Negro formations of the La Providencia Group. The microbiota is dominated by Leiosphaeridia species (L. minutissima, L. ...
Late Quaternary environmental changes in southernmost South America reflected in marine calcareous macro-and-microfossils
(Elsevier, 2012-11)
Late Quaternary environmental changes, especially sea-level fluctuations and glacial advances and retreats, affected the distribution of the benthic marine fauna which inhabited the Beagle Channel in southernmost South ...
Southern hemispheric westerlies control the spatial distribution of modern sediments in Laguna Potrok Aike, Argentina
(Springer, 2010-12)
We studied the internal lake processes that control the spatial distribution and characteristics of modern sediments at the ICDP (International Continental Scientific Drilling Program) deep drilling site in Laguna Potrok ...
A multi-proxy approach to paleoenvironmental changes in the southwestern Río de la Plata area (Argentina) during Late Pleistocene
(Pergamon-Elsevier Science Ltd, 2019-04)
In the southwestern margin of the Río de la Plata (Argentina), mining works have uncovered deposits that correspond to the last glacio-eustatic cycle (<120 Ky). Because deposits of this cycle are rare in the area, the ...
Pleistocene calcareous macro-and-microfossils from the southernmost tip of South America as environmental proxies during the last interglacial period
(Pergamon-Elsevier Science Ltd, 2009-12)
Macro-and-microfossils, including molluscs, cirripeds, echinoids, foraminifers and ostracods area significant component of a Pleistocene marine unit located along the southern coast of the BeagleChannel, on Navarino Island, ...
On the mismatch in the strength of competition among fossil and modern species of planktonic Foraminifera
(2019-12-01)
Aim: Many clades display the macroevolutionary pattern of a negative relationship between standing diversity and diversification rates. Competition among species has been proposed as the main mechanism that explains this ...
