The analysis of the ostracod assemblages collected in the lower glauconitic horizon of the Arcillas de Gibraleon Formation permits to delimitate two levels: a) Basal level, with the presence of infralittoral, outer platform and even bathyal species, indicative of a condensed section with the evolution from subaerial environments to outer platform environments in a 60 cm-thickness interval; and b) Upper level, deposited in a outer platform-upper bathyal environment, according to the glaucony features and the ostracod assemblages.
