The Xinlong Formation (sometimes called the "Napai Formation", or misspelt as "Napan Formation") is an Early Cretaceous geologic formation in Guangxi, southern China.Xinlong Formation at Fossilworks.org
Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.Weishampel, et al. (2004). "Dinosaur distribution." Pp. 517-607.
