The basal samples of this horizon show both shallow-water and epibathyal taxa, a mixture also found in ostracods that may characterize the transition toward deeper conditions. In the upper samples, deepneritic and epibathyal species are dominant, indicating a moderate-deep environment (150-300 m) in which was deposited most of the glauconitic horizon}, publisher = {Sociedad Geológica de España}, title = {Los foraminíferos bentónicos del horizonte glauconítico inferior de la Formación «Arcillas de Gibraleón» (Depresión del Guadalquivir, SO España)}, title = {Foraminifers of the lower glauconitic level of the Arcillas de Gibraleón Formation (Guadalquivir Basin, SW Spain)}, author = {González-Regalado Montero, María Luz and Ruiz Muñoz, Francisco and Abad de los Santos, Manuel and Pendón Martín, José Gabriel and Tosquella Angrill, Josep}, }
