The Morro Solar Group (Spanish: Grupo Morro Solar) is a stratigraphic group of Mesozoic-aged sedimentary formations exposed near Lima, Peru. The groups formations more specifically of Berriasian and Valanginian age (Early Cretaceous) and overlies the Jurassic and underlies the Cretaceous . The Morro Solar Group is intruded by sills of andesitic composition.[1] Together with the Casma and , the Morro Solar Group contains clastic volcanosedimentary material derivative of the Mesozoic .[2] The formations of the group hosts mostly local fossils which do not have counterparts for biochronological correlation in other regions.[3]

The formations of the Morro Solar Group are: La Herradura Formation (Spanish: Formación La Herradura), whose sediments reflect a marine near-shore deposition environment,[4] the Valanginian Salto del Fraile Formation (Spanish: Formación Salto del Fraile), and the (Spanish: Formación Marcavilca).[1] The Salto del Fraile Formation is equivalent to the basal part of the found further inland.[5]
