Asociaciones de bivalvos de! Triásico en España

Asociaciones de bivalvos de! Triásico en España

Abstract

Durante el Triásico la Península lbérica formaba parte del extremo más occidental del Tethys. En los sedimentos del Triásico Medio-Superior (Anisiense-Noriense) de las Cordilleras Ibérica, Catalana y Béticas externas (Prebético y Subbético) se pue­den diferenciar, en ocasiones, hasta tres niveles carbonatados: Muschelkalk inferior (Anisiense), Muschelkalk superior (Ladi­niense) y las Dolomías de la Formación Imón (Noriense), y algunas intercalaciones carbonaticas en el Subbético (Carniense). El registro fósil es escaso y esta mal conservado. Durante un siglo (1853-1954), los trabajos paleontológicos sobre el Mus­chelkalk espanol se referían a aspectos puntuales y muestran una gran confusión en la sistemática. En este trabajo se sinteti­zan los resultados obtenidos en la investigación paleontológica de los bivalvos triásicos de España durante los últimos diez anos. Por el momento, se han podido diferenciar varias asociaciones caracteriesticas: una en el Anisiense, tres en el Ladinien­se, dos en el Ladiniense-Carniense, una en el Carniense y una en el Noriense. El registro de bivalvos esta relacionado con ambientes protegidos de rampas carbonatadas someras. Las especies de bivalvos no tienen significado bioestratigráfico de pequeño rango pero sus asociaciones permiten caracterizar !as diferentes intercalaciones carbonatadas. La mayoría de los taxa son comunes en la cuenca del Tethys.
