A bioestratigraphic study has been carried out with the aid of ammonoids from the Lower Ladinian of the SE Calasparra section (Eastern of the Betic Cordillera). The section is formed by 89 m of do- lostones and fossiliferous limestones from the Muschelkalk facies. From the study of 11 successive levels with ammonoids, three biozones have been distinguished: Brotzeni Zone (Upper Anisian), Curionii Zone (Lower Ladinian) and Epigonus Zone (Upper Ladinian). Moreover, the Curionii Zone could be subdivided in two Subzones: Curionii Subzone and Awadi Subzone. The ammo- noid assemblages are typical from the Sepharadic Province, which include numerous species in common with Sinai and Negev (Israel). These assemblages can be correlated with other areas of Spain (Catalonia and Minorca) and the Tethys Province, due to the presence of two species of wide geographic distribution, Eoprotrachyceras curionii and "Eoprotrachyceras" cf. gredleri, which are recorded in the lower part of the Curionii and Epigonus Zones respectively.
