Abstract
This paper analyzes the ostracod faunas obtained from the lower and middle sections (170.4 m-89.3 m depth) of the core �Huelva� (SW Guadalquivir Basin). These sections were deposited in an epibathyal to outer shelf environment, where these organisms were extremely rare compared with other groups of microfossils. The Tortonian-Messinian boundary appears to mark a temporary shallowing of the environment, characterized by progressive disappearance of epibathyal forms.
