Plesiosaurs (diapsida, sauropterygia) from late cretaceous (late campanian-early maastrichtian) marginal marine environments from north Patagonia

During the late Campanian and early Maastrichtian, Northern Patagonia suffered the first stage of the Atlantic marine ingression that reached the Neuquén Basin. The Allen and La Colonia formations show the early stages of this change, and were deposited in a complex association of marginal marine en...

description During the late Campanian and early Maastrichtian, Northern Patagonia suffered the first stage of the Atlantic marine ingression that reached the Neuquén Basin. The Allen and La Colonia formations show the early stages of this change, and were deposited in a complex association of marginal marine environments, including coastal and marine deposits (i.e., flood plains, estuaries and lagoons). The plesiosaurs from the Allen and La Colonia formations included at least three species, each with a distinctive morphotype, representing a high diversity in the Late Cretaceous. The only species that preserved cranial material, Sulcusuchus erraini Gasparini and Spalleti, is a strange polycotylid characterized by the presence of deep grooves in the rostrum and mandible. The other two species correspond to aristonectine and non-aristonectine elasmosaurids. The former are distinguished by relatively large skulls and a high number of teeth compared to other elasmosaurids, whereas the non-aristonectine elasmosaurids are characterized by their relatively small body sizes, despite being adult specimens.

Las formaciones Allen y La Colonia evidencian las primeras etapas de este cambio, habiéndose depositado en una asociación de ambientes irregulares que incluyen depósitos marino-marginales (es decir de llanuras mareales, estuarios y lagunas costeras). Los plesiosaurios de las formaciones Allen y La Colonia incluyen al menos tres especies, cada una con un morfotipo distintivo, lo que representa una alta diversidad hacia fines del Cretácico. La única especie con material craneano preservado es Sulcusuchus erraini Gasparini y Spalleti, un extraño policotílido caracterizado por la presencia de profundos surcos en el rostro y la mandíbula. Las otras dos especies corresponden a elasmosáuridos aristonectinos, caracterizados por tener cráneos relativamente grandes y elevado número de dientes comparados con otros elasmosáuridos y a elasmosáuridos no aristonectinos, que se destacan por su relativo pequeño tamaño, a pesar de tratarse de ejemplares adultos.Fil: O'gorman, Jose Patricio.
