Even they can not be used to establish and identify biostratigraphical or chronostratigraphical units, the reelaborated fossils are useful for sequential and discontinuities analysis, for location of source areas of sediments, as indicators of paleocurrents, and for identification of sedimentary environments and paleogeography. Some reelaborated fossils are the only existing record of eroded sediments. They permit the obtention of data on episodes of the Geological History of which the stratigraphic record is not available anymore. https://hdl.handle.net/20.500.14352/60688 Utilidad sedimentológica y estratigráfica de los fósiles reelaborados.
