The Cajones Formation is a Turonian geologic formation of central Bolivia. The fluvial sandstones in Amboró National Park preserve fossils of Yacarerani boliviensis.[1][2] The formation is correlated with the Adamantina Formation of the Paraná Basin in Brazil and the Bajo de la Carpa Formation of the Neuquén Basin in Patagonia, Argentina.[3]
