The Marília Formation is a geological formation in Minas Gerais state of southeastern Brazil. Its strata date back to the Maastrichtian, and are part of the Bauru Group.
The fossil-bearing Serra da Galga and Ponte Alta members were originally thought to belong to this formation but were split off into the Serra da Galga Formation in 2020.
