- W1622267476 abstract "Resumen. En este articulo se analiza la composicion de la tafoflora exhumada en cerro Centinela, Chile central, la cual se halla incluida en sedimentos del miembro inferior de la Formacion Navidad, asignados al Mioceno Tardio-Plioceno Temprano. Sobre la base de los antecedentes conocidos respecto de los requerimientos ecologicos de las especies actuales relacionadas, sumados a informacion de los fosiles mismos, se plantea que el conjunto paleofloristico corresponde a una mixtura tafonomica y que incluye elementos provenientes de diversas paleocomunidades. El analisis de los diferentes escenarios posibles, en tal situacion, es contrastado con la informacion sedimentologica, lo que permite postular que dichas paleocomunidades se encontraban segregadas espacialmente en un area que podia extenderse desde los centros volcanicos, por el este, hasta el litoral marino por el oeste. El presente analisis sugiere, ademas, un clima mas humedo y calido que el actual para la region.Abstract. THE FOSSIL FLORA FROM CERRO CENTINELA (CHILE, VI REGION): VEGETATION AND CLIMATE IN CENTRAL CHILE AT THE END OF MIOCENE-BEGINNING OF THE PLIOCENE.In this article, the composition of the taphoflora from cerro Centinela, central Chile, is analyzed. This fossil flora is included in sediments of the lower member of the Navidad Formation, which is assigned to Late Miocene-Early Pliocene. This was achieved on the basis of available data about modern related species, adding some information from the fossils themselves. A taphonomic mixture, including elements collected in different paleocommunities, is postulated. The analysis of the different possible scenarios, in this situation, is contrasted against sedimentological information to conclude that these paleocommunities were spatially separated in a broad area, which could be extended from as far as the volcanic centers, in the east, to the seashore in the west. Furthermore, the analysis suggests a more humid and warmer climate than the actual one in the region." @default.
