El límite de las Biozonas Transversarium y Bifurcatus (Oxfordiense Medio) en la Cordillera Ibérica nororiental: discontinuidades y lagunas estratigráficas asociadas
(Sociedad Geológica de España, 1995)A biostratigraphic study of Middle Oxfordian, Transversarium to Bifurcatus Zone rocks in the northeastern Iberian Chain (Spain) has been taken along six detailed sections providing very close ammonite control. The deposition ... -
La aplicación del concepto de especie biológica en Ammonites y su interés en Sistemática y Bioestratigrafía: la subfamilia Perisphinctinae Steinmann 1891 en el Oxfordiense Medio de la Provincia Submediterranea
(Sociedad Geológica de España, 1996)Despite the importance of Perisphinctidae ammonite family as a tool (or biogeographic correlation and biostratigraphy during the Oxfordian, these studies are frequently hampered by the intraspecific morphological and ... -
La subfamilia Ataxioceratinae (Ammonoidea) en el Oxfordiense Superior de la Provincia Submediterránea: origen y evolución
(Sociedad Geológica de España, 1996)The subfamily Ataxioceratinae Buckman arises at the turn of the Middle-Upper Oxfordian (Upper Jurassic) in the South-European Platform, spreading mostly throughout the Submediterranean province during Upper Oxfordian-Lower ... -
Las subdivisiones bioestratigráficas de la Biozona Bimammatum (Oxfordiense Superior) en la Cordillera Ibérica nororiental: facies y amplitud de las discontinuidades
(Sociedad Geológica de España, 1995)Middle to Upper Oxfordian rocks in the northeastern Iberian Chain (Spain) are formed by bioclastic sponge limestones (Yatova Fm.). The development of the sponge facies, however, appears geographically and stratigraphically ...
