Abstract
Fossil leaves and pollen obtained from sediments in the type-locality of Ligorio Marquez Formation, south of Chile Chico, in the XI Region, 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 Concepcion-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.
