Operator bias and replicability in comparative taphonomic studiesEl sesgo del operador en la replicabilidad de los estudios tafonómicos comparativos
(Sociedade Brasileira de Paleontologia, 2016-12)
The operator effect is a well-known analytical bias already quantified in some taphonomic studies. However, the influence of operator bias in the replicability on taphonomic studies has still not been considered. Here, we ...
Chronological distribution and disturbance factors to evaluate population dynamics in Western Pampas, Argentina
(Pergamon-Elsevier Science Ltd., 2015-01)
The radiocarbon chronology of the sites and cultural sequences is, at the regional level, a benchmark for evaluating different types of processes: cultural, demographic, taphonomic, environmental. Although it is assumed ...
Chronology and human settlement in northeastern Patagonia (Argentina): patterns of site destruction, intensity of archaeological signal, and population dynamics
(Elsevier, 2013-03)
Temporal frequency distributions are used to assess the chronology and continuity of human occupation at different spatial scales, differential landscape use and demographic patterns throughout time. These issues were ...
Past population dynamics in Northwest Patagonia: An estimation using molecular and radiocarbon data
(Academic Press Ltd - Elsevier Science Ltd, 2016-01)
Studying demographic changes in past human populations is of great interest due to their role in processes of cultural change as well as the biological evolution of populations. Despite this, a general consensus about the ...
A marine connection between parnaíba and paraná basins during the eifelian/givetian transition: Review and new data
(2016-01-01)
A long-lived marine seaway between the Parnaíba and Paraná basins occurred during a global marine transgression between Brazilian intracratonic basins (except for the Solimões Basin) in the latest Eifelian/earliest Givetian ...
Taphonomic differences in molluscan shell preservation in freshwater environments from the southeastern Pampas, Argentina
(Society for Sedimentary Geology, 2014-12)
Actualistic studies in freshwater environments are scarce, limiting the interpretation of paleoenvironmental information obtained from the fossil record. The objectives of this study are to assess the taphonomic factors ...
Analytical Bias in Taphonomic Studies of Macro-invertebrates: (Paleo)Environmental and (Paleo)Ecological ImplicationsViés Analítico em Estudos Tafonômicos com Macroinvertebrados: Implicações (Paleo)Ambientais e (Paleo)Ecológicas
(Universidade de São Paulo, Instituto de Geociências, 2009)
Ten years of actualistic taphonomic research in the Pampas region of Argentina: Contributions to regional archaeology
(Pergamon-Elsevier Science Ltd, 2018-10)
Over the last decade, we have conducted an actualistic taphonomic research program in the Humid Pampas of Argentina, in order to build a corpus of information about the taphonomic agents and processes characterizing this ...
Compositional Fidelity and Taphonomy of freshwater Mollusks from Three Pampean shallow Lakes of ArgentinaFidelidad Composicional y Tafonomía de moluscos dulceacuícolas en tres lagos someros pampeanos de Argentina
(Asociacion Paleontologica Argentina, 2017-04)
Three shallow lakes from the southeastern pampas, which are different in their physicochemical characteristics, were studied with the aim of comparing live/dead fidelity and preservation of mollusk shells. The studied lakes ...
Radiocarbon trends in the pampean region (Argentina). biases and Demographic patterns during the final late pleistocene and holocene
(Pergamon-Elsevier Science Ltd, 2015-01)
This paper compiles a database of radiocarbon dates of archaeological sites that are currently available for the Pampean region. Based on the probability distribution of radiocarbon dates from this database, major temporal ...
