Río Colorado Subgroup

Geologic subgroup in Argentina

Not to be confused with Colorado Formation.

The Río Colorado Subgroup, formerly named as Río Colorado Formation, is a Late Cretaceous (Santonian to Early Campanian) geologic subgroup of the Neuquén Basin in northern Patagonia, Argentina. It belongs to the Neuquén Group and contains the Anacleto and Bajo de la Carpa Formations. The subgroup overlies the Río Neuquén Subgroup and is overlain by the Allen Formation of the Malargüe Group, separated by an unconformity dated to 79 Ma.[1] Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.[2]
