AB A detailed analysis of the Upper Messinian-Lower Pliocene at the northern border of the Bajo SeguraBasin (BSB) has been carried out. Trace fossils of firm- and rockground were collected, aiding in therecognition of three ichnofacies: Glossifungites (types A and B), Entobia and Gnathichnus. The ichnologicaldata provide evidence that the Pliocene flooding of the BSB, after the Messinian Salinity Crisis, was developedin two pulses. In the first one, the ingression penetrated only along the paleovalleys and produced acoastal trasgressive lag (P0). In the second one, the ingression overflowed the margins of the paleovalleysand extended throughout the entire northern margin, also producing a coastal transgressive lag in the baseof the P2 system. The record of the Entobia and Gnathichnus ichnofacies in the clasts of both lags evidencesa relatively fast deepening-upward trend in both the transgressions
