Devonian and Carboniferous pre-Stephanian rocks from the Pyrenees
(Instituto Geológico y Minero de España, 2002)A stratigraphic description of the Devonian and Carboniferous pre-Variscan rocks of the Pyrenees is presented. The successions are grouped into sedimentary domains that replace the "facies area" proposed by previous authors ... -
Early Devonian eurypterids with Bohemian affinities from Catalonia (NE Spain)
(Museu Geològic del Seminari de Barcelona, 1997-07)The sequence of early Lower Devonian (Lochkovian) strata with dominant anchimetamorphic shales of the Olorda Formation yielded numerous remains of eurypterids. These belong to the Family Pterygotidae and are represented ... -
Estratigrafía del Serpukhoviense y el Bashkiriense inferior (Carbonífero) en la provincia de Pliegues y Mantos, Zona Cantábrica
(Sociedad Geológica de España, 2004-07)The lateral relationships among the San Adrián, Canalón and Olaja members of the upper part of the Alba Fm. are discussed. These rocks are considered to be parts of a carbonate ramp developed from latest Viséan or early ... -

Problemas en el reconocimiento del límite Misisipiense/Pensilvaniense en el Norte de la Península Ibérica
(2006-03-21)Se discute el origen de una nueva sub-especie del conodonto Declinognathodus noduliferus y su probable aparición más temprana que D. inaequalis en el norte de la Península Ibérica. -
Silúrico, Devónico y Carbonífero pre- y sin-varisco de los Pirineos
(Instituto Geológico y Minero de España, Sociedad Geológica de España, 2004)Se describe la variación en la sedimentación entre el Silúrico y el Carbonífero sibn-varisco en los Pirineos. Una correlación entre las diferentes unidades estratigráficas es propuesta y se revisa la división en dominios. -

Stratigraphy of lower Cambrian and unconformable lower Carboniferous beds from the Valls unit (Catalonian coastal ranges)
(Elsevier, 2000)The Palaeozoic rocks outcropping around Valls are divided into two stratigraphic units. The boundary between both is an unconformity. The lower unit is composed by nearshore platform sediments and a Lower Cambrian age is ... -
Taxonomy and evolutionary significance of some "gnathodus" species (conodonts) from the Mississippian of the northern Iberian Peninsula
(Instituto Geológico y Minero de España, 2004)A new species of Gnathodus, G. joseramoni, is defined and Gnathodus cantabricus Belka & Lehmann is revised from the study of some new conodont associations and analysis of previous data from the Cantabrian Mountains and ... -
