The Xinlong Formation (sometimes called the "Napai Formation", or misspelt as "Napan Formation" [1]) is an Early Cretaceous geologic formation in Guangxi, southern China. [2]
Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation. [3]

Asiatosaurus [4] | A. kwangshiensis [4] | Teeth, three cervical vertebrae and ribs | Indeterminate sauropod | |||
Datanglong [5] | D. guangxiensis | Last dorsal (back) vertebra (according to the descriptors the fourteenth), continues over the five sacral vertebrae, and ends with the second tail vertebra.
