Zusammenfassung
The present work describes and comments on 11 species of asteroliths recorded in the Guadalquivir Basin and adjacent D.S.D.P. sites; the species belong to the groups Eu-discoaster quinqueramus, Eu-discoaster brouweri and Eu-discoaster pentaradiatus, and were found together with other species which cannot be adscribed to these or other groups; such species will be described in later works. A series of comments regarding the conservational status and paleoecological aspects of the species discussed is provided. The sediments where the species are found cover an interval in the Tortonian-Lower Pliocene.
