Abstract

The micro-morphologic and bioerosive features, analyzed in the Benzú shelter (Ceuta), allow us to deduce an erosion marine surface elaborated onto dolomite triassic substrate. The Entobia-Gastrochaenolites Ichnoassociation and Entobia ichnofacies denote high energy coastal or shallow marine environment with low sedimentation rates. Two phases are differentiated in the evolution of these bioerosive structures: the first one defined by great borings of Gastrochaenolites, and the second recorded by bioerosive activity of Entobia and truncation of both, the previous borings and the cliff surface.
