  Marília Formation (Brazil) | |
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.[1]
The fossil-bearing Serra da Galga and Ponte Alta members were originally thought to belong to this formation[2] but were split off into the Serra da Galga Formation in 2020.[3]
