Abstract
Se estudia la fauna de Condrichtios del nivel glauconítico de la
sección tipo de la Formación "Arenas de Huelva". Se han reconocido 16 tipos,
indicadores de un medio cálido y una profundidad moderada (50-150 m) durante el
Plioceno Inferior en este sector de la Depresión del Guadalquivir.
A rich fauna of selachians and batoids is recorded from the glauconitic level of the section-type of the "Sands of Huelva" Formation. Sixteen types were recognized in the unit studied, which indicate both a temperate-climate and a moderate depth (50 to 150 m) during the Lower Pliocene in this sector of the Guadalquivir Basin.
