Upper Triassic Palaeobotany of Biobío river valley, Chile: Filicopsida Class.

Abstract: RESUMENSe describen restos fósiles de la Clase Filicopsida presentes en los estratos marinos y continentales del valle inferior del río Biobío (37ºS/73ºW) denominados formación Santa Juana y asignados al Triásico Superior (Cárnico-Nórico) de la Región del Biobío, Chile. La tafoflora incluye diez especies, de las cuales ocho son primeros registros para el Triásico de esta región: Gleichenites quilacoyensis Leppe y Moisan sp. nov., Asterotheca rigbyana rigbyana Herbst, Rienitsia colliveri Herbst, Dictyophyllum f… Show more

“…The beetles and hemipterans described from the Upper Triassic Santa Juana Formation, were found in association with a rich floristic assemblage, including ferns, sphenophytes, seed ferns, ginkgoaleans, cycadophytes, conifers and gymnosperms, in which plant-insect interactions have also been recognized. The overall good preservation of the specimens indicate that the biota grew and deposited close to water bodies, possibly in abandoned channels or oxbows in a floodplain or deep waters of a lake setting (Martins-Neto et al, 2003;Nielsen, 2005;Leppe et al, 2006;Moisan et al, 2010;Gnaedinger et al, 2014;Pérez & Pérez, 2015).…”
