The Sao Khua Formation is a middle member of the Khorat Group. It consists of an alteration of pale red to yellowish-gray, fine to medium-grained sandstone and grayish-reddish brown siltstone and clay. Rare pale red to light gray conglomerates, containing carbonate pebbles, are also characteristic of this Formation. This geological formation in Thailand, dates to the Early Cretaceous age.
Dinosaur remains are among the fossils that have been recovered from the formation.[1]
