The Guadiato Area is located on Córdoba province (SW Spain), with a direction NW-SE. It is composed of Mississipian rocks (upper Viséan-Lower Serpukhovian), which are divided in three structural units: «Fresnedoso» Unit, «Sierra Castillo» Unit, and «San Antonio-La Juliana» Unit. The foraminiferal assemblages of calcareous rocks from these units have been studied.
