RT Journal Article T1 Principales estructuras biogénicas en el Plioceno marino de la Cuenca del Baix Llobreeat (Catalunya) A1 Gibert, J. M. de A1 Martinell, Jordi AB The Pliocene basin of the Baix Llobregal (Catalonia) has proportionated an important record of trace fossils. These are a result of both bioerosion activity in hard substrates and bioturbation in the soft sediments. The ich-notaxa found indicate a shallow sedimentary environment.
