The Toqui Formation is a geological formation in the Aysén Region of southern Chile. It has been dated to the Tithonian stage of the Late Jurassic by uranium–lead dating of zircons, providing ages between 148.7 ± 1.4 Ma and 147 ± 1.0 Ma. It consists of a sequence of clastic sedimentary sandstones and conglomerates, interbedded with volcanic tuffs and ignimbrite. The dinosaurs Chilesaurus and indeterminate diplodocids and the mesoeucrocodylian Burkesuchus are known from the formation. The formation was deposited in a fluvio-deltaic environment.
