Fidelity of molluscan assemblages from the touro passo formation (pleistocene-holocene), southern brazil: taphonomy as a tool for discovering natural baselines for freshwater communities
(Sepm-soc Sedimentary Geology, 2011-07-01)
This study is the first assessment of mollusk fossil assemblages relative to the compositional fidelity of modern mollusk living and death assemblages. It also shows that the sedimentary record can provide information on ...
A Late Pleistocene macrobenthic assemblage in Caleta Patillos, northern Chile: paleoecological and paleobiogeographical interpretations
(Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2008)
The temporal resolution of epibiont assemblages: Are they ecological snapshots or overexposures?
(2006-05-01)
The effects of time averaging on the fossil record of soft-substrate marine faunas have been investigated in great detail, but the temporal resolution of epibiont assemblages has been inferred only from limited-duration ...
Conifer fossil woods from the Santa Marta Formation (Upper Cretaceous), Brandy Bay, James Ross Island, Antarctica
(Academic Press Ltd - Elsevier Science Ltd, 2017-09)
Conifer fossil woods from the Santonian to lower Campanian Santa Marta Formation are anatomically studied in detail. The wood flora is dominated by conifers, mainly Araucariaceae. Conifer fossil woods represent 84% of the ...
Depositional environment of Stelloglyphus llicoensis isp. nov.: a new radial trace fossil from the Neogene Ranquil Formation, south-central Chile
(Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2008)
El bosque petrificado de Piedra Chamana: preliminary paleoecological interpretations of a late middle Eocene fossil assemblage
(Sociedad Geológica del PerúPE, 2013)
The Piedra Chamana Fossil Forest in northern Peru, which is associated with Calipuy volcanics dated at 39 Ma, includes a large amount of fossil wood occurring across an 8-km-long area. In one part of the site, woods are ...
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, ...
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 ...
First Fossil Assemblage of Darkling Beetles (Coleoptera: Tenebrionidae) from Buenos Aires, Argentina: Evidence of Dry Climate during the Late Pleistocene in the Humid Pampas
(Polish Academy of Sciences, 2016-12)
Late Pleistocene outcrops exposed in Buenos Aires province, Argentina, represent one of the most informative sources for paleoecological studies on South American fauna and flora. Several proxies have been used for studying ...
Depositional environment of Stelloglyphus Ilicoensis isp nov.: a new radial trace fossil from the Neogene Ranquil Formation, south-central Chile
(SERVICIO NACIONAL GEOLOGIA MINERVA, 2008-07)
Stelloglyphus llicoensis isp. nov. is a large radial, discoidal to ellipsoidal trace fossil with a central shaft and single to bifurcating branches radiating from different levels. A 30 m thick measured section of the ...
