          Abstract

          La icnofacies de Glossifungites es reconocida en el contacto entre las formaciones Navidad (Miembro Rapel) y La Cueva, Plioceno de la Cordillera de la Costa, Chile. La suite de Glossifungites está caracterizada por una alta densidad de ? Gastrochaenolites isp. La superficie está cubierta por un lag transgresivo. Las excavaciones están rellenas en forma pasiva por arena y grava proveniente de la capa suprayacente. La superficie es interpretada como un límite de secuencia (superficie co-planar de erosión de nivel del mar bajo y de ravinamiento trangresivo).

          Translated abstract

          The Glossifungites ichnofacies is recognized at the boundary between the Navidad (Rapel Member) and La Cueva formations, Pliocene of the Coastal Cordillera, Chile. The Glossifungites suite is characterized by a high density of ? Gastrochaenolites isp. The surface is mantled by a transgressive lag. Burrows are passively infilled with sand and gravel coming from the overlying bed. The surface represents a sequence boundary (a co-planar surface of lowstand erosion and transgressive ravinement).
