Abstract

In the Neogene sediments of the Lower Segura Basin (Eastern Betic Cordillera) have been studied three localities with fossil micromammals. They yielded a fauna which date the stratigraphic units MS-IV (Upper Tortonian-Messinian) and P-I (Lower Pliocene). The two older, named Castro and Pantano de Elche (Pantel) date the base of the Upper Turolian (zone MNI2) and the Ventian (zone MN13) respectively; they both belongs to the unit MS-IV. The younger one, locate in the Barranco de Fayona (Fayona) indicates a Lower Ruscinian age (zone MNI4) of the unit P-I, which was considered until now as Upper Pliocene.
