Introduction The '''Luohandong Formation''' is an Early Cretaceous geologic formation of the Ordos Basin in Inner Mongolia, China. The formation was initially dated to the earliest Cretaceous; Valanginian to Barremian, but later dating established an Aptian to Albian age. Dinosaur remains are among the fossils that have been recovered from the formation. Pterosaur fossils have also been recovered from the formation.
