The Grès supérieurs Formation (French for "Upper sandstone") is a geological formation in Laos whose strata date back to the Aptian to Albian stages of the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.[1] It is equivalent to the Khok Kruat Formation of Thailand.

Fossil content

The Grès supérieurs Formation has also yielded remains of indeterminate iguanodontians, as well as ornithopod and sauropod tracks.
