Abstract
Se estudia la asociación de arqueociatos hallada en niveles carbonáticos de la Formación Pedroche que afloran, de forma dispersa, a lo largo de la Carretera Córdoba-Villaviciosa, al Norte de la ciudad de Córdoba. Los fósiles seencuentran a techo de la sucesión, en niveles tabulares o biostromos con mesoestructura trombolítica. Se describe una nueva especie, Erismacoscinus lucanoi nov. sp. y la asociación estudiada está constituida por tres géneros, Protopharetra, Erismacoscinus y Nochoroicyathus. La edad asignada a estos materiales se corresponde con las Zonas I-III de arqueociatos (Perejón & Moreno-Eiris, 2006) Ovetiense inferior (Cámbrico Serie 2, Piso 3).
The archaeocyathan assemblage from carbonate beds of the Pedroche Formation that crop out dispersed along the Cordoba-Villaviciosa Road, North of Cordoba city, is studied. The fossils are in thrombolite biostromes at the top of the succession. A new species is described, Erismacoscinus lucanoi nov. sp. The archaeocyathan assemblage stu- died is consisted of three genera, Protopharetra, Erismacoscinus and Nochoroicyathus. The age assigned to carbonate materials is I-III archaeocyathan Zones (Perejón & Moreno-Eiris, 2006) Early Ovetian (Cambrian Series 2, Stage 3)
