| Abstract (English): |
Bryozoan fauna from the Lower Devonian (Pragian-Emsian) deposits of the Ossa-Morena Zone (SW Spain) comprises twenty-eight species: one cyclostome, two cystoporates, sixteen trepostomes, five cryptostomes, and four fenestrates. Three new genera with one new species, respectively, are described: cyclostome Diploclemella serenensis n. gen. n. sp., trepostome Cordobella tenuis n. gen. n. sp., and cryptostome (rhabdomesine) Serenella dubia n. gen. n. sp. Three trepostome species are new: Leptotrypa parva n. sp., L. modesta n. sp., and Boardmanella spinigera n. sp. Ten species are described in open nomenclature. The studied bryozoan fauna shows high morphological and taxonomical diversity, comprising mostly species of moderate size. The assemblage is clearly dominated by branched ramose and encrusting growth forms. The studied bryozoan fauna shows some distinct palaeobiogeographic relations to the bryozoans from the Lower Devonian of NW Spain, Morocco, and Czech Republic. [ABSTRACT FROM AUTHOR] |

La fauna de briozoos de los depósitos del Devónico Inferior (Pragiense-Emsiense) de la Zona de Ossa-Morena (SO de España), comprende ventiocho especies: un ciclostomado, dos cystoporados, dieciséis trepostomados, cinco cryptostomados y cuatro fenestrados. Se describen respectivamente tres nuevos géneros con sus respectivas especies tipo: el ciclostomado Diploclemella serenensis n. gen. n. sp., el trepostomado Cordobella tenuis n. gen. n. sp., y el cryptostomado (rhabdomesino) Serenella dubia n. gen. n. sp. Tres especies de trepostomados son nuevas: Leptotrypa parva n. sp., L. modesta n. sp., y Boardmanella spinigera n. sp. Diez especies se describen en nomenclatura abierta. La fauna de briozoos muestra una alta diversidad morfológica y taxonómica, comprendiendo principalmente formas de tamaño moderado. La asociación está claramente dominada por formas ramosas e incrustantes. La fauna de briozoos muestra claras relaciones paleogeográficas con los briozoos del Devónico Inferior del norte de España, Marruecos y República Checa. [ABSTRACT FROM AUTHOR] |
