dc.description.abstractA detailed analysis of the Upper Messinian-Lower Pliocene at the northern border of the Bajo Segura Basin (BSB) has been carried out. Trace fossils of firm- and rockground were collected, aiding in the recognition of three ichnofacies: Glossifungites (types A and B), Entobia and Gnathichnus. The ichnological data provide evidence that the Pliocene flooding of the BSB, after the Messinian Salinity Crisis, was developed in two pulses. In the first one, the ingression penetrated only along the paleovalleys and produced a coastal trasgressive lag (P0). In the second one, the ingression overflowed the margins of the paleovalleys and extended throughout the entire northern margin, also producing a coastal transgressive lag in the base of the P2 system. The record of the Entobia and Gnathichnus ichnofacies in the clasts of both lags evidences a relatively fast deepening-upward trend in both the transgressionsen_US
