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 ros...
