The main lithostratigraphical units of the northern flank of the Sant Corneli anticline are briefly described and discussed. Some new units are erected and, one of these, the Montagut limestones unit group together some latter members: Montagut Mb., Clot de Moreu Mb. and El Grau Mb. A biostratigraphic survey of Coniacian and Santonian outcrops from the St Corneli anticline northern flank is presented...
Albian Rudist faunas from southern Apennines (Abruzzi, Matese Mounts) and Apula (Murge andGargano), hitherto mainly considered Cenomanian, are dated after micropaleontological assemblages. They consist of 12 taxa belonging to the Requieniidae, Monopleuridae, Polyconitidae, Radiolitidae and Caprotinidae (?). Our study, even preliminary, calls attention to the specificity of the Albian fauna relatively...
A palynological study of the Burdigalian historical stratotype and neighbouring outcrops in the Bordeaux area indicates that they span the Burdigalian and part of the Serravallian time interval. Special palynological processing techniques for crag deposits were used to successfully extract abundant and diverse dinocyst floras. Several biostratigraphical markers are identified that characterize Burdigalian...
For the first time a detailed ammonite biostratigraphy is presented for the Oxfordian (Upper Jurassic)in the Central Sierra Norte in Mallorca (Balearic archipelago, Spain). Three sections (Coll d'Es Gats, Cuber and Alfabia) have been studied on the basis of a continuous sampling of 10–20 cm thick samples in ammonitico rosso successions 2.3–5 m thick. Ammonite-rich but benthos-poor faunal assemblages...
Ferralsia is known from the southern side of the Montagne Noire (France), the Görlitz Synclinorium(Germany), and the Ossa-Morena zone (Iberian Peninsula). The finding of Ferralsia saxonica in the reference section of the Marianian stage (a Lower Cambrian chronostratigraphic unit of the Iberian Peninsula) allows us to consider it as a potential taxon for correlation within the Cambrian Mediterranean...
Dans le Moyen Atlas méridional, au-dessus des Marnes à gypse cénomaniennes, les couches de base des calcaires de la Formation d'Amghourzif sont datées du Cénomanien supérieur non terminal par des foraminifères de la sous-famille des Rhapydionininae. Cet âge est confirmé par la mise en évidence, dans les couches sus-jacentes, d'ammonites de la zone à Vascoceras gr. cauvini et d'une association de foraminifères...
L'étude des faunes d'ammonites - plus de 25 taxons - et de leur succession biostratigraphique dans unecoupe exceptionnellement complète et fossilifère du Haut-Atlas central de la région de Rich (Maroc) a permis la mise en évidence de 10 unités biochronologiques élémentaires (=assemblages) pour une période débutant au sein de la partie terminale du Sinémurien inférieur et s'achevant avec le Sinémurien...
La biostratigraphie et la chronostratigraphie de la séquence de gisements de mammifères de Crevillentesont analysées, donnant comme résultat une zonation détaillée à base de rongeurs. Les gisements sont attribués au Turolien, ou, en terminologie de stratigraphie marine, au Tortonien et Messinien. La corrélation de la limite Tortonien/Messinien avec la séquence de gisements à faunes de rongeurs peut...
La fauna conchífera de braquiópodos del Devónico Inferior del Dominio Palentino (N de España) se conoce mal, pese a su abundancia y buen estado de conservación. No obstante, dicha fauna permite correlaciones internacionales más precisas que las posibles con las faunas equivalentes, mejor conocidas, del Devónico Astur-Leonés. En los últimos tiempos, se concede mucha atención a las reconstrucciones...
