Cretaceous reptiles of Asia

Eupodophis is an extinct genus of snake from the Late Cretaceous period. It has two small hind legs and is considered a transitional form between Cretaceous lizards and limbless snakes. The feature, described as vestigial, was most likely useless to Eupodophis. The type species Eupodophis descouensi was named in 2000 and resides now in the paleontology section of the Mim Museum in Beirut, Lebanon. The specific name is dedicated to the French naturalist Didier Descouens.

Hyphalosaurus (meaning "submerged lizard") is a genus of freshwater aquatic reptiles, belonging to the extinct order Choristodera. They lived during the early Cretaceous period (late Barremian to early Aptian age), about 123-120 million years ago. The genus contains two species, H. lingyuanensis from the Yixian Formation and H. baitaigouensis from both the Yixian and Jiufotang Formation of Liaoning Province, China. They are among the best-known animals from the Jehol Biota, with thousands of fossil specimens representing all growth stages in scientific and private collections.

left|thumb|Closeup of the skull Ikechosaurus is an extinct genus of choristodere reptile which existed in China and Mongolia during the Early Cretaceous. It contains the species Ikechosaurus sunailinae and Ikechosaurus gaoi. It belongs to the crocodilian-like clade Neochoristodera and was initially assigned to the Champsosauridae by Sigogneau-Russell (1981). Compared to other neochoristoderes, Ikechosaurus has a rather simple dentition, lacking the speciations seen in latter species. It also has parasphenoid palatal teeth, a feature not seen in any other choristodere.

Rugosuchus (meaning "uneven or wrinkled crocodile", in reference to texturing on its upper jaw bones) is an extinct genus of neosuchian crocodyliform from the Cretaceous of China. It is known from most of a skull, a partial postcranial skeleton, and a second partial skeleton including part of the hips. It was described by Xiao-Chun Wu and colleagues in 2001, with R. nonganensis as the type species. At the time of its description, it was the most complete crocodyliform from northeastern China, and only the second known.
