The Río Limay Subgroup is a geological unit of the Neuquén Group in the Neuquén Basin of Neuquén, Mendoza and Río Negro Provinces, northern Patagonia, Argentina. The strata date back to the Late Cretaceous ( Early Cenomanian to Early Turonian. The Río Limay Subgroup overlies the Lohan Cura Formation, separated by an unconformity dated to 98 Ma. [1] Dinosaur remains are among the fossils that have been recovered from the formations it contains. [2]
Having previously been considered a distinct formation, the Río Limay Subgroup is now considered a member of the larger Neuquén Group, and itself contains several specific geological formations (from youngest to oldest):
