Fossil associations from the middle and upper Eocene strata of the Pamplona Basin and surrounding areas (Navarre, western Pyrenees)

Fossil associations from the middle and upper Eocene (Bartonian and Priabonian) sedimentary succession of the Pamplona Basin are described. This succession was accumulated in the western part of the South Pyrenean peripheral foreland basin and extends from deep-marine turbiditic (Ezkaba Sandstone Formation) to deltaic (Pamplona Marl, Ardanatz Sandstone and Ilundain Marl formations) and marginal marine deposits (Gendulain Formation). The micropalaeontological content is high. It is dominated by foraminifera, and common ostracods and other microfossils are also present. The fossil ichnoasssemblages include at least 23 ichnogenera and 28 ichnospecies indicative of Nereites, Cruziana, Glossifungites and ?Scoyenia-Mermia ichnofacies. Body macrofossils of 78 taxa corresponding to macroforaminifera, sponges, corals, bryozoans, brachiopods, annelids, molluscs, arthropods, echinoderms and vertebrates have been identified. Both the number of ichnotaxa and of species (e. g. bryozoans, molluscs and condrichthyans) may be considerably higher. Body fossil assemblages are comparable to those from the Eocene of the Nord Pyrenean area (Basque Coast), and also to those from the Eocene of the west-central and eastern part of South Pyrenean area (Aragon and Catalonia). At the European scale, the molluscs assemblages seem endemic from the Pyrenean area, although several Tethyan (Italy and Alps) and Northern elements (Paris basin and Normandy) have been recorded. Palaeontological data of studied sedimentary units fit well with the shallowing process that throughout the middle and late Eocene occurs in the area, according to the sedimentological and stratigraphical data.

Contraprestaciones por los servicios financieros del Consulado de México y sus miembros: los fondos extraordinarios para la guerra contra Gran Bretaña, 1779-1783

Nueva España aportó la mayor parte de los recursos que sostuvieron a las fuerzas armadas españolas durante la guerra contra Gran Bretaña que se desarrolló en el Caribe entre 1779 y 1783. En el artículo se analizan las medidas a las que recurrieron las autoridades reales para obtener recursos extraordinarios del Consulado y varios mercaderes de la ciudad de México. Asimismo se exponen algunas de las contraprestaciones que negociaron a cambio de dichos servicios financieros y se plantean diversas hipótesis acerca de los motivos económicos, sociales y políticos que los llevaron a colaborar con el monarca, teniendo en cuenta los negocios que realizaban durante el conflicto bélico y la forma en que eran afectados por la reciente apertura comercial.
