Ostracode Research Activities inARGENTINA
Correspondent: Alwine Bertels <bertels@tango.gl.fcen.uba.ar>
Ballent, Sara C. The work was centered on the study of Lower Cretaceous marine ostracoda of the Argentina Neuquén and Austral basins. Tending to reach optimum hidrocarbon prospection, the elaboration of a reliable correlation squeme, based on biostratigraphic data as well as paleobiogeographic results is one or the main purposes. Together with Robin Whatley of Aberystwyth (Wales), who visited Argentina during the months of May and June of 1998, two manuscripts are prepared. In one of them, based on the variation of the percentages at the Suborder/ Superfamily levels, the changes in the structure of the marine Ostracoda microfaunas from west-central Argentina, during the Hettangian-Tithonian interval, are analized. In the second a review of the genus Procytherura Whatley, of wide gondwanic distribution, during the Jurassic and lower Cretaceous is made as well as the probable usefulness of some other taxa as biostratigraphic markers are evaluated.
Bertels, Alwine. Alwine continues directing the doctoral theses of: (1) Laura Ferrero, Miocropaleontología y paleoecología (ostrácodos y foraminíferos) del Cuaternario del sudeste de la provincia de Buenos Aires and (2) Dina E. Martínez, Ostrácodos marinos y no marinos del Cuaternario del Sur de la provincia de Buenos Aires, consideraciones paleoambientales. In these theses, the research comprises the study of Foramininifera and marine and non-marine Ostracoda, the last being compared with some recent taxa collected in neighbouring regions. Current work includes: (1) the continuation of micropaleontological studies of nonmarine ostracodes of the Nahuel Huapi Group, of middle Tertiary age, which crop out in the Rio Negro province; in part it is carry out with Gabriela Cusminsky; (2) Holocene marine and non marine ostracodes of the Buenos Aires province; some of them are developed together with Dina E. Martínez and Cecilia Laprida and (3) the study of fossil ostracodes of southern Patagonia maars; in these analysis is working now a geologist, Bettina Ercolano, who lives in southern Patagonia; I hope she will begin and continue studing Ostracodes.
Cusminsky, Gabriela C. Gabriela is dedicated to the study of ostracodes within the frame of the development of several projects: (1) Comahue lakes; (2) study of lacustrine ostracoda of Patagonia, in colaboration with Antje Schwald (Postdam University, Germany); the name of this project is PATO and is directed by V. Markgraf and D. Aristeguis; (4) Lacustrine ostracodes of the northwestern region (Puna) of Argentina, being the project "Climatic change in arid Andes" and directed by H. Weit, and (5) Recent ostracoda and quiromids in northern Patagonia; the study is focused in the birth-rate of ostracoda derived from resistant eggs.
Echevarría, Alicia E. She continues devoted to the study of Tertiary Ostracoda from Patagonia and, related to the topic, her current work is the systematic of marine Ostracoda of the Oligocene Centinela Formation of Santa Cruz Province, Argentina.
Ferrero, Laura. Laura continues working on her doctoral theses "Micropaleontología y paleoecología (ostrácodos y foraminíferos) del Cuaternario del sudeste de la provincia de Buenos Aires", and is carrying out a research project about the evolution of the sedimentary environments during the last 20000 years in the Quequén Grande river basin.
Laprida, Cecilia. Cecilia continues her work on Quaternary marginal marine ostracods and foraminifers of norheastern Buenos Aires province, Argentina. Main focus is on taxonomic aspects as well as on paleoecological interpretation of the successions. Current research activities include studies of Ostracoda from several outcops of Holocene marginal marine environments belonging to the Destacamento Río Salado and Las Escobas Formations.
Martínez, Dina E. Dina continues working on her doctoral Theses and on non-marine and marine ostracods of the southern region of the Buenos Aires province. The paper in press was mentioned above (see Bertels)
