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).
