Chemical taphonomy and preservation modes of Jurassic spinicaudatans from Patagonia: A chemometric approach
(Cambridge University Press, 2018-11)
Spinicaudatans ('clam shrimps') are small branchiopod crustaceans enclosed in a chitinous bivalved carapace that is often the only preserved element in the fossil record. However, few studies have analyzed the preservation ...
Plant taphonomy in a lake affected by volcanism (Agua de la Zorra formation, Upper Triassic) Mendoza, Argentina
(Society for Sedimentary Geology, 2020-07)
Volcanic eruptions have an impact on the paleoecology of plant communities and their preservation in the fossil record. The aim of this contribution is to evaluate the influence of volcanism on plant preservation in ...
Tafonomia experimental sobre peixes: geobiológicas e zooarqueológicas
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Biotecnologia e Monitoramento Ambiental - PPGBMA-SoCâmpus Sorocaba, 2018-03-12)
Experimental Taphonomy has assisted in the simulation and understanding of variables that affect the fidelity of paleontological and zooarchaeological records. In this experimental study was tested the role of thermal ...
Taphonomy and taphofacies analysis of lingulid brachiopods from Devonian sequences of the Paraná Basin, Brazil
(2010)
The extreme abundance of lingulid valves in some outcrops of the Devonian sequences of the Paraná Basin, and their absence in others, where other benthic taxa dominate, was the starting point to the present research. ...
Preservation of Cyclotella meneghiniana Kützing (Bacillariophyceae) Along a Continental Salinity Gradient: Implications for Diatom-Based Paleoenvironmental Reconstructions
(Asociación Paleontológica Argentina, 2018-07)
In order to elucidate the effect that physico-chemical lake characteristics exert on diatom valve preservation, the taphonomic signatures of the target taxon Cyclotella meneghiniana Kützing was assessed in twenty five ...
Chemical analyses of the earliest pigment residues from the uttermost part of the planet (Beagle Channel region, Tierra del Fuego, Southern South America)
(Academic Press Ltd - Elsevier Science Ltd, 2008-06)
This paper presents the results of chemical analyses of the organic and inorganic fractions of pigment residues found in three archaeological sites located in the Beagle Channel region, Tierra del Fuego, Southern South ...
Chemometric study of the preservation modes of Athabaskia anax (Trilobita, Cambrian Precordillera, Mendoza, Argentina): Implications for taxonomy
(Elsevier, 2021-08)
Selected pygidia of the middle Cambrian corynexochid trilobite Athabaskia anax (Walcott 1916) from the Miaolingian Series of San Isidro (Precordillera, Mendoza, Argentina) are analyzed for the first time using scanning ...
Micromammal taphonomy and site formation process of Nutria Mansa 1 archaeological site (Buenos Aires, Argentina)
(John Wiley & Sons Ltd, 2018-09)
This paper presents the results of the taphonomic analysis of the micromammal bone remains recovered from Nutria Mansa 1 (NM1), an archaeological site located in the Pampean plains, Argentina. This campsite was occupied ...
Lichen bioerosion on fossil vertebrates from the Cenozoic of Patagonia and Antarctica
(Taylor & Francis, 2011-01)
Different traces occur on fossil bones and teeth coming from the Early Miocene Gaiman Formation (Patagonia, Argentina). Most traces were attributed to the action of terrestrial and marine predators and scavengers. However, ...
Assessing the influence of saline and alkaline environments in the preservation of pampean diatoms: an experimental approachEvaluación de la influencia de los ambientes salinos y alcalinos en la preservación de las diatomeas pampeanas: Un enfoque experimental
(Asociación Paleontológica Argentina, 2019-09)
Diatom dissolution is controlled by environmental conditions prevailing during fossilization. In Pampean shallow lakes, diatom dissolution showed important correlations with gradients of salinity, pH, carbonate, and ...
