Asociación fitolítica del Pleistoceno inferior en el sudoeste de la provincia de Entre Ríos (Argentina)

Abstract

La Formación Alvear (Pleistoceno inferior) posee una gran importancia en la sedimentología del Cuaternario de la región, por la potencia de sus sedimentos y su amplía distribución regional en el SO de la provincia de Entre Ríos. En la presente contribución se describe la asociación fitolítica de la Formación Alvear en su área tipo, ia localidad del Puerto General Alvear (departamento Diamante). Este estudio corresponde al primer registro fósil de esta formación. La asociación fitolítica esta compuesta por fitolitos esféricos (steqrnatas), asociados con fitolitos con forma de flabelos (células buliformes), macro y micropelos, fitolitos elongados (células largas) y fitolitos cónicos, halterios y sillas de montar (células cortas). La afinidad botánica de esta asociación indica la presencia de una paleocomunidad dominada por palmeras (Arecaceae) y gramíneas (Poaceae) del tipo meso y megatérmicas.

The Alvear Formation (Lower Pleistocene) is a quaternary formation with regional importance as consequences of their regional distribution in SW of Entre Ríos province. The present contribution describes the phytoJith assemblage of the Alvear Formation in their typica! area, the General Alvear Port locality (Diamante departrnent), presenting the first fossil record of this forrnation. The phytoiith assemblage, is composed by spherical phytoliths (steqrnata), associated with fan-shaped phytoliths (bulliform cells), macro and micro-hairs. elongated phytoliths (iong cells), conical phytoliths, durnbell and saddle phytoliths (short cells). The botanicallikeness of these assemblage indicates the presence of a paleocomunity dominated by palms (Arecaceae) and grass (Poaceae) of meso and megatermic types.
