Los Hammatoceratinae (ammonitina) del Toarciense y Aaleniense en la Cordillera lbérica y Cordillera Cantábrica oriental. Implicaciones paleobiogeográficas.

Abstract

Los Hammatoceratinae constituyen una de !as subfamilias de ammonoideos que estan presentes en los materiales del Lias y del Dagger del Norte de España, con un registro escaso en relación al resto de los ammonoideos. Se han distinguido 43 espe­cies y 7 generos que se distribuyen desde la Zona Variabilis (Subzona Illustris) del Toarciense hasta la Zona Discites del Bajo­ciense. El estudio de las diferentes morfologías y la identificación de !as diferentes asociaciones tafonómicas, permiten reco­nocer en ellas elementos procedentes de áreas mesogeas y del NW de Europa. El origen de este grupo podría encontrarse en determinadas formas mesogeas, que pudieron invadir áreas de plataforma. En la mayoría de los casos los elementos registra­dos corresponden a conchas derivadas procedentes de regiones más o menos alejadas de! lugar de enterramiento. Así mismo existen elementos que pudieron colonizar algunas áreas de la Cuenca lbérica y de la Cuenca Vasco-Cantábrica, durante deter­minados episodios de las Zonas Insigne, Alensis y Opalinum.
