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]

Genus Species Location Stratigraphic position Material Notes Images
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. The sacrum is attached to a left ilium with the upper parts of the left pubic bone and the left ischium, and one piece of the right ilium A member of Carcharodontosauria
Fusuisaurus[6] F. zhaoi[6] Partial pelvis and caudal vertebrae A titanosauriform
Liubangosaurus[7] L. hei[7] Fifth to ninth dorsal vertebrae An eusauropod
Napaisaurus[8] N. guangxiensis[8] Right ilium and ischium An iguanodontian
Prodeinodon[9] P. kwangshiensis Several teeth, fragmentary tibia, fragmentary fibula Indeterminate theropod
Psittacosauridae?[8] Indeterminate Several different taxa of possible Psittacosaurid classification.
Siamosaurus[10] Indeterminate, possibly S. fusuiensis[10] Four teeth Spinosaurid originally known as "Sinopliosaurus" fusuiensis[11]
