| dc.description | Fossil leaves and pollen obtained from sediments in the type-locality of Ligorio Márquez Formation, south of Chile Chico, in the XI Región, southern Chile, are reported in this paper. The megafossils include twenty leaf species, fourteen of them being Lauraceae. In fossil pollen, coming from ca. 15 m higher stratigraphic levels than the paleomegaflora, Pteridophyta, Pinophyta and Magnoliophyta are represented through seven, two and four palynological species, respectively. Affinities of this fossil flora with the Concepción-Arauco paleoflora are proposed. A Late Paleocene age and a wet paleoclimate with high mean annual temperatures and low mean variation range are suggested by this fossil assemblage. | en-US |
| dc.description | Los resultados del estudio de improntas foliares y polen fosiles recuperados de sedimentos de la Formacion Ligorio Marquez, en su localidad tipo, al sur de Chile Chico, en la XI Region de Chile, son presentados en este articulo. La paleomegaflora incluye veinte organoespecies, catorce de ellas Lauraceae. El elenco palinologico recuperado, que proviene de niveles estratigraficos ca. 15 m superiores a aquellos que contienen la paleomegaflora, esta constituido por siete especies polinicas de Pteridophyta, dos de Pinophyta y cuatro de Magnoliophyta. Los resultados paleobotanicos permiten postular afinidades de esta paleoflora con aquella de Concepcion-Arauco, y que la edad mas probable de la formacion sea paleocena superior. Los nuevos antecedentes paleofloristicos indican, ademas, un paleoclima humedo, de altas temperaturas medias anuales y bajo rango de variaciones medias. | es-ES |
