Paleoflora (Fabaceae y Anacardiaceae) de la Formación Andalhuala (Plioceno Inferior), provincia de Catamarca, Argentina

Abstract

Se describe una flora constituida por impresiones de hojas colectada en la localidad Pie del Médano, (sobre ruta nacional 40, km 914-915) en la provincia de Catamarca. Procede de la Formación Andalhuala que en esa localidad tiene una datación de 5.22 ± 0.9 Ma, lo que la ubica en el Plioceno Inferior. La flora está compuesta por Fabaceae, (Prosopis sp. a, Eriosema pliocenica sp. nov. y Macroptilium sp.) y Anacardiaceae (Lithrea sp. y Schinus aff. terebinthifolia Raddi). Esta asociación se habría desarrollado bajo un clima cálido, integrando vegetación xerofítica y bosques higrófilos.

A leaf impression flora from the Pie del Médano locality, (on national route 40, km 914-915) in Catamarca Province, is described. It comes from the Andalhuala Formation, which at that locality was dated as 5.22 ± 0.9 MY, indicating a Lower Pliocene age. The flora is composed of Fabaceae (Prosopis sp. a, Eriosema pliocenica Anzótegui and Horn sp. nov. and Macroptilium sp.) and Anacardiaceae (Lithrea sp. and Schinus aff. terebinthifolia Raddi). The association indicates a warm climate, xerophyte vegetation and riparian vegetation along river banks.
