Mulichinco Formation
The Mulichinco Formation is a geological formation in Argentina. It is Valanginian in age and is predominantly terrestrial, being deposited at a time of marine regression in the Neuquén Basin, and predominantly consists of siliciclastic rocks.[1] Dinosaur remains have been found in the formation, including those of the dicraeosaurid Pilmatueia[2] and carcharodontosaurid Lajasvenator.[3]
