Abstract
Ostracods from the Moguer section (Huelva province, SO Guadalquivir Basin) are here studied. 49 speces belong to 26 genera are described. The comparation with biostratigraphical studies executed in this materials and Atlantic and Mediterranean biozonations allow us to atribute a Lower Pliocene age (Tabianian) to this section. The analysis of available bathymetric data supports the view that the habitat of the Pliocene associations was shalow, near-shore with temperature over 16° C and salinities between 38-39‰.

La ornamentación se compone de un reticulado poligonal grosero con paredes abruptas muy evidente en los bordes posterior y ventral; éste no llega a alcanzar el margen anterior convirtiéndose en un punteado irregular principalmente en forma de coma
Podría tratarse de ejemplares juveniles de esta especie, ya que Aranki (1987) sugiere que las formas pleistocenas y actuales son más reticuladas que los re· presentantes pliocenos
