Primitive Vascular Plants and Microfossils from the Río Seco de los Castaños Formation, San Rafael Block, Mendoza Province, Argentina

Abstract: In this contribution we describe fossil plant remains from Río Seco de los Castaños Formation, at San Rafael Block, Mendoza Province, Argentina. The fossil plants comprise non-forked and forked axes without or with delicate lateral expansions, which are assigned to Bowerophylloides cf. mendozaensis and Hostinella sp. We refer them to primitive land plants and discuss about their systematic affiliation. Furthermore, we mention the presence of a diverse acritarch assemblage present in the same lithostratigraphic… Show more

“…In the Atuel Creek area fragments of primitive vascular plants are described and assigned to the Lower Devonian and marine microfossils such as prasinophytes, spores and acritarchs were found by D. Pöthe de Baldis (cf. Morel et al 2006;this volume) in the RSC, indicating shallow water conditions near the coastline.…”

“…Hacia el sector más austral del terreno Cuyania se encuentran los afloramientos del Bloque de San Rafael, allí es posible encontrar varias unidades pre-carboníferas entre las que se destacan para este lapso temporal las Formaciones Rio Seco de los Castaños y La Horqueta. La primera asignada a una edad silúrica tardío-devónica temprana, caracterizada por facies humocky que indicarían un rápida depositación de los sedimentos y acción de tormentas, la unidad cuenta con presencia de detritos vegetales, que por su estado de preservación sugiere que las fuentes continentales no se encontraban muy alejadas al depocentro (Morel et al, 2017). Por su parte la Formación La Horqueta fue depositada en un ambiente marino, encontrándose dominada principalmente por metaareniscas, metapelitas y escasos metaconglomerados.…”
