Resumo
Thè marine arid lacustrine Upper Neogene sediments in the Southwestern sector of the Guadalquivir Basin (Lepe-Ayamonte area, Huelva, Spain), are basically characterized by four distinte ichnofacies: Cruziana, Skolithos, mixed Cruziana-Skolithos, Gnathichnus and GlóssifungiièS ichrìófacies. The stages of ichnofacial evolution provides several palaeòenviromentàl keys for these materials, as bathimetry, hydrodihamic energy, salinity and type of substratum
