Generación de estructuras de carga y pseudonódulos asociados a la impresión de icnitas de grandes vertebrados continentales, posiblemente de dinosaurios, en el Jurásico superior y Cretácico inferior de Alpuente (Valencia)

Abstract

Some sinsedimentary cilindrical structures, in vertical position, are present in fluvial and beach deposits (Late Jurassic and early Cretaceous) wich outcrop in the Rambla de la Arquela, Alpuente (Valencia). Theese structures are the result of plastic deformation and, eventually, of the downward fluidification and injection of sand. Field evidences suggest that were produced because localized vertical load on the surface of unconsolidated sands and clays, and can be related to icnites of mesozoic terrestrial vertebrates, probably dinosaurs
