Conodontos de la "Caliza de Pelmatozoos" (Ordovícico Superior), Norte de Sevilla, Zona de Ossa-Morena (España)/Conodonts from the "Pelmatozoan Limestone" (Upper Ordovician), northern Sevilla, Ossa-Morena Zone (Spain)

Several limestone levels of the "Caliza de Pelmatozoos" were sampled for conodonts in sections of the Cerrón del Hornillo and Valle synclines. The conodont fauna includes: Amorphognathus ordovicicus, A. aff. ordovicicus, Amorphognathus sp., Amorphognathus? sp., Drepanoistodus cf. suberectus, Drepanoistodus? sp., Hamarodus europaeus, Icriodella cf. superba, Istorinus erectus, Panderodus gracilis, Plectodina tenuis?, Sagittodontina robusta, Scabbardella altipes, Scabbardella sp A., Walliserodus amplissimus? y Walliserodus? sp. This association is attributed to the Amorphognathus ordovicus Zone by the presence of the index species, and to the Sagittodontina-Scabbardella Biofacies of the Mediterranean Province of conodonts by the relative abundance of these two taxa. This fauna is close related to coeval associations from several localities of the Iberian Peninsula, except that of the Malaguide Complex, but the presence of Plectodina and Drepanoistodus suggest possible faunal exchange with Anglo-Baltic faunas.
