    Revision of the upper Cretaceous rudists from Northwestern Peru.

    Revision of the Upper Cretaceous of northwestern Peru led to new discoveries of rudists and allowed to specify their taxonomy and stratigraphic repartition. Different species have been identified: Biradiolites cf. jamaicensis Trechmann 1924, Radiolites cf. macroplicatus Whitfield 1897, Praebarrettia sparcilirata (Whitfield, 1897) of Late Campanian age, Macgillavryia nicholasi (Whitfield, 1897), of “Middle” to Late Maastrichtian age. During Campanian and Maastrichtian times, rudists of Peru show palaeobiogeographic affinities with those of the Mexican and Caribbean domains. A palaeogeographic route for rudist migrations probably existed at that time along the Caribbean arc and the Curaçao-Ecuador coastline

    Regards d’aujourd’hui sur les comptabilitĂ©s mĂ©diĂ©vales : des chambres des comptes Ă  la Cour des comptes

    Cette contribution propose une rĂ©flexion sur la pratique des chambres des comptes mĂ©diĂ©vales Ă  partir de la pratique contemporaine de la Cour des comptes, dans les contrĂŽles, dans la procĂ©dure et dans la structure des comptes. Les contrĂŽles restent essentiellement formels mais sont plus ciblĂ©s autour d’un objectif, non pas de repĂ©rer toute irrĂ©gularitĂ©, mais de se donner une assurance raisonnable sur les comptes. La procĂ©dure montre la permanence de trois grands principes depuis l’origine des chambres des comptes : le caractĂšre juridictionnel, l’annualitĂ© de la reddition de comptes et la responsabilitĂ© personnelle du comptable. Ce dernier principe commence pourtant Ă  apparaĂźtre un peu anachronique au regard de la structure comptable actuelle, qui a hĂ©ritĂ© de distinctions essentielles progressivement opĂ©rĂ©es par rapport Ă  la comptabilitĂ© rudimentaire du Moyen Âge. En revanche, le premier de ces trois principes continue Ă  constituer un moteur d’évolution de la Cour des comptes en 2011 !This paper offers a reflection on the medieval practices of accounting chambers through the perspective of the modern Cour des comptes, encompassing the audit, procedure and structure of accounts. The audit remains essentially formal, focussing increasingly on the more general task of asserting a reasonable measure of reliability of the accounts rather than to unearth each and every irregularity. Procedure reveals the permanence of the three great founding principles of accounting chambers : their judicial nature, the principle of yearly accountability and the personal responsibility of the accountant. This last aspect, however, has progressively lost of its importance in regard to our current accounting structure, which has evolved some essential differences from the basic accounting system of the Middle Ages. The first of these aspects, however, remains in 2011 a driving force for the evolution of the Cour des comptes !Esta contribuciĂłn propone reflexionar sobre la prĂĄctica de las cĂĄmaras de cuentas medievales a partir de la prĂĄctica contemporĂĄnea del Tribunal de Cuentas de Francia, en los controles, el procedimiento y la estructura de las cuentas. Los controles, hoy en dĂ­a, son esencialmente formales pero se centran mĂĄs en un objetivo. No se trata tanto de averiguar irregularidades como de llegar a una seguridad razonable en las cuentas. El procedimiento revela la permanencia de tres grandes principios desde el origen de las cĂĄmaras de cuentas : el carĂĄcter jurisdiccional, la anualidad en la rendiciĂłn de cuentas y la responsabilidad personal del encargado de manejar fondos. Este Ășltimo principio, sin embargo, empieza a parecer anacrĂłnico dentro de la estructura contable actual, que heredĂł distinciones esenciales establecidas progresivamente desde la contabilidad sumaria de la Edad Media. En cambio, ÂĄel primero de los tres principios sigue siendo un motor de evoluciĂłn del Tribunal de Cuentas en 2011 !Dieser Beitrag hat zum Ziel, die Praxis der mittelalterlichen Rechnungskammern mit Hilfe der heutigen Praxis des Rechnungshofs zu untersuchen: Es geht dabei um die Kontrollen, die Verfahren und die Rechnungsstruktur. Die Kontrollen sind hauptsĂ€chlich formell und haben als vorrangiges Ziel sicherzustellen, dass die Rechnungen korrekt ausgestellt wurden. Drei Grundprinzipen dominieren seit dem Anfang der Rechnungskammer: die ÜberprĂŒfung der rechtlichen Merkmale, der jĂ€hrliche Rhythmus der ausgestellten Rechnungen und die persönliche Verantwortung des Schreibers. Das letzte Prinzip ist heute relativ unzeitgemĂ€ĂŸ, das erste dafĂŒr immer wichtiger fĂŒr die Entwicklung des Rechnungshofes im Jahre 2011

    Late Cretaceous marine transgressions in Ecuador and northern Peru: a refined stratigraphic framework.

    Study of ammonites and bivalves along selected sections on the Andean margin of northern Peru and Ecuador has made it possible to recognize correlatable marine transgressions and to propose a refined stratigraphic framework for the Upper Cretaceous of the region. Six maximum flooding events are recognized: latest Turonian–early Coniacian (major event), late Coniacian–early Santonian, late Santonian–early Campanian, mid Campanian–early late Campanian (major event), early Maastrichtian (major event), and terminal early Maastrichtian. Most of these events can be correlated with global eustatic sea-level rises, but their relative manifestations indicate that the Andean margin was already being deformed by the late Cretaceous “Peruvian” tectonic events. The onset of fine-grained clastic sedimentation in the Oriente and East-Peruvian basins in the mid Turonian–earliest Coniacian is taken as the first event of the “Peruvian” phase. The Campanian regional transgression in the Peruvian-Ecuadorian forearc zones concealed the “Peruvian” deformational event. The latter caused a palaeogeographic upheaval, indicated by the subsequent development of a NNE-trending forearc basin, which extended from Paita in northwestern Peru to northern Ecuador. In the forearc zones only short-lived transgressions are recorded in the late Campanian and early Maastrichtian as a result of nearly continuous tectonic activity. This culminated with a significant tectonic event in the late Maastrichtian, causing a widespread hiatus
