Estructuras de escape de anémonas marinas (Conichnus indet. isp.) y sedimentación en depósitos litorales del Complejo Basal Transgresivo del sector central de la Cuenca del Guadalquivir (SO España)

Abstract

The study of faunistic associations, ichnology and sedimentology of coastal deposits, that crops out in the central sector of pasive margin of the Guadalquivir Basin, allows us to make an approached reconstruction of ambient features which dominated in this sector of the basin during Tortonian. High dimensions escape structures, interpreted like trace make by marine anemones (Conichnus indet. isp.), receive especial attention on this paper. Their presence shows arrives of an enormous amounts of sediment to the beach from nearer deltaic system
