Geological formation in Brazil
The Serra da Galga 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] It was originally considered a member of the Marília Formation.[2]
Dinosaur remains are among the fossils that have been recovered from the formation.[3]
The serra de galga formation is interpreted as having been deposited under a hot,dry climate [4] . The formation is considered to be of a Late Maastrichtian age [5] [6].

Three distinct titanosaurids denoted as forms A, B, and C have been found in Area 4.[7] Titanosaurine remains are known from Areas 1 and 2.[7] Indeterminate theropod remains known from Area 1.[7] Indeterminate maniraptor remains known from Area 1.[7] Indeterminate abelisaurid remains are known from Areas 1 and 2.[7] The abelisaurids appeared to have came in a variety of sizes, some grew large.[9] Enantiornithines have also been recovered.[10] An indeterminate abelisauroid tibia, potentially referrable to noasauridae, is known as well [11] .
