“…This unit is overlain by up to ~80 m of multistoreyed cross-bedded conglomerates, fi ne-grained sandstones, minor mudstones, and foraminiferan-and mollusc-rich limestones that were interpreted as fan-delta deposits (Gómez & Pedraza 1994;Gómez et al 2003). To the southwest, in the Upper Magdalena Valley Basin, lateral equivalent units (La Tabla and Monserrate Formations; Montes et al 2005;Ramon & Rosero 2006) are continental (braided river deposits; Ramon & Rosero 2006). Palaeocurrent and provenance data for these units indicate a western source located in the present-day Central Cordillera (Gómez et al 2003;Montes et al 2005;Ramon & Rosero 2006).…”

In this chapter we present a synthesis of the Cenozoic evolution of the Amazonian foreland basin system, based on a review of the estimated ages, lithology and sedimentary structures, palaeontological content, and inferred depositional environments of sedimentary units in the basin. In addition, we have calculated maximum sedimentation rates for the Cenozoic formations of the northern Peruvian foreland basin and integrated these with existing data on sedimentation rates, subsidence analysis, migration of depocentre and depositional environments. Based on this information we propose a model for the Cenozoic evolution of the Amazonian foreland. The sedimentary architecture of this foreland basin indicates that Cenozoic evolution was marked by several periods, which were roughly synchronous and of similar effect, along the entire Amazonian foreland basin system. Tectonic loading of the Andes of Colombia, Ecuador, Peru and northern Bolivia, and development of the Amazonian foreland, was initiated during Late Cretaceous-Paleocene times and followed by an unloading stage during the Early-Middle Eocene period. The Middle-Late Eocene marine transgression and the increase in sedimentation rates, associated with westward migration of the depocentre, were all indicative of a renewed phase of tectonic loading of the Peruvian Western Cordillera and the Ecuadorian and Colombian Eastern Cordillera. Subsequent Oligo-Miocene increase in sedimentation rates and further migration of the depocentres towards the present-day sub-Andean zone, are all indicative for a thrust-induced uplift and loading of the Eastern Cordilleras of Peru, Bolivia and Colombia. This Oligo-Miocene loading stage maintained high subsidence rates that favoured the sedimentation of aggradational fl oodplain and coastal plain and tidally infl uenced deposits. Nevertheless, the processes that controlled the Early-Middle Miocene marine ingressions remain to be determined. Late Miocene ongoing thrust tectonic loading of the Eastern Cordillera, initial structuring of the sub-Andean zone and the onset of the main phase of Andean surface uplift induced fl exural subsidence in the foredeep depozones of the entire Amazonian foreland basin. This process also drove the Late Miocene marine transgressions that characterized the fi lled stage of the Ecuadorian, Peruvian and Bolivian Amazonian foreland basin system. Valley incisions and full relief development in the hinterland during the Late Miocene-Pliocene provided increased sediment supply and overfi lled the Amazonian foreland basin system. Finally, the fl at-slab subduction of the Nazca ridge induced Pliocene (~4 Ma) uplift of the Fitzcarrald Arch and subdivided the Amazonian foreland basin into the northern and southern Amazonian foreland basins.

“…The sedimentary Cretaceous in the basin was deposited in this environment. The progressive oblique collision between the Caribbean plate and the Northern margin of South America during the end of the Cretaceous and the Early Cenozoic, generated a series of deformation events conditioning the evolution of the Northern Andes and its adjacent basins (Case, Duran, Lopez, & Moore, 1971, Villamil & Pindell, 1998, Montes, Hatcher, Restrepo-Pace, 2005.…”

“…Los restos fósiles se encontraron en una capa de limolita calcárea físil que buza hacia el sureste con una inclinación menor a 5°. Esta capa hace parte de la unidad denominada Nivel de Lutitas y Arenas, de edad Campaniano (de Porta, 1965;Montes et al, 2005). La unidad fue definida por de Porta (1965) en la sección Piedras-La Tabla, en la misma región en la que se encontró el mosasaurio ( fig.…”

En este artículo se da a conocer un nuevo mosasaurio hallado en Colombia. El fósil fue extraído de capas del Campaniano, al norte de la población de Coello, departamento del Tolima. Se trata de un esqueleto casi completo y articulado, en cuyas cavidades se preservaron restos de tejidos blandos. Se ha determinado como una nueva especie del género Eonatator, E. coellensis, con base en la sistemática propuesta en 2005 por Bardet y otros. La anatomía de la parte anterior del cráneo, así como la morfología y las inter-relaciones de los huesos de la cintura pélvica y de los miembros, constituyen un nuevo aporte a la definición del género. El espécimen colombiano representa el mosasaurio halisaurino más completo conocido hasta ahora en el mundo y ofrece posibles evidencias de gestación interna en los mosasaurios. Palabras clave: Eonatator, Mosasauridae, Campaniano, Colombia ABSTRACTIn this study a new mosasaur found in Colombia is given out. The fossil was extracted from Campanian rocks, North of the town of Coello, Tolima Department. It is a nearly complete articulated skeleton with soft tissue remains preserved in its cavities. It was determined as a new species of the genus Eonatator, E. coellensis, based on the systematics proposed in 2005 by Bardet and others. The anatomy of the anterior part of the skull, as well as the morphology and the inter-relationships of the bones of the pelvic girdle and limbs, constitute a new contribution to the genus definition. The Colombian specimen represents the most complete halisaurine mosasaur known so far in the world, and provides new evidences of ovoviviparity in mosasaurs.
