SHALLOW MARINE MACROBIOEROSION IN THE NEOGENE OF CATALONIA

FOREWORD The marine Neogene is well represented in Catalonia and it has been well known and studied for more than a century. The marine Miocene is represented in the Penedès and Camp de Tarragona Basins, while the marine Pliocene occurs in the Alt Empordà, Baix Llobregat and Baix Ebre basins. The objective of the fieldtrips is to visit several localities in three of those basins (Penedès, Camp de Tarragona and Alt Empordà) which are of special interest for bioerosion specialists. Most of the localities that will be visited correspond to ancient rocky shores, but also bioerosion in reefs and shelly substrates will be observed. The ichological content of all these Neogene localities is characterized by a Gastrochaenolites-Entobia assemblage which corresponds to the Entobia ichnofacies of Bromley and Asgaard (1993). This ichnofacies is typical for nearshore environments since the Jurassic. The fieldtrips will be completed with some non-ichnological stops devoted to visi
