Anshunsaurus was a marine reptile with a long neck, slender skull, and long, paddle-like tail. In comparison to its long trunk, the limbs are very small. Anshunsaurus is characterized by a long jugal bone in the skull, fused postorbital and postfrontal bones around the eyes, a maxilla that forms part of the margin of the eye socket, a humerus with large crests, and a large fibula. The type species of Anshunsaurus, A. huangguoshuensis, was named in 1999 from the Ladinian or Carnian age Falang Formation in Guanling County. Although several complete skeletons are known, most specimens are crushed in either dorsal (top) or ventral (bottom) view. The holotype of A. huangguoshuensis, IVPP V11835, is preserved in dorsal view while a second specimen, IVPP V11834, is preserved in ventral view. Base

abstract	Anshunsaurus was a marine reptile with a long neck, slender skull, and long, paddle-like tail. In comparison to its long trunk, the limbs are very small. Anshunsaurus is characterized by a long jugal bone in the skull, fused postorbital and postfrontal bones around the eyes, a maxilla that forms part of the margin of the eye socket, a humerus with large crests, and a large fibula. The type species of Anshunsaurus, A. huangguoshuensis, was named in 1999 from the Ladinian or Carnian age Falang Formation in Guanling County. Although several complete skeletons are known, most specimens are crushed in either dorsal (top) or ventral (bottom) view. The holotype of A. huangguoshuensis, IVPP V11835, is preserved in dorsal view while a second specimen, IVPP V11834, is preserved in ventral view. Based on these specimens, A. huangguoshuensis grew to about 3.5 metres (11 ft) in length. Although the tip is not preserved in any specimen, the tail made up at least half of the animal's length.[1] A second species, A. wushaensis, was named in 2006 from Xingyi.[2] A. wushaensis is slightly smaller than A. huangguoshuensis and has a smaller head relative to its body length. It also has shorter neural spines with ridges on their upper surface, a shorter fourth digit on the hand, a well-developed entepicondyle on the humerus, and a shorter jugal bone.[3] A juvenile specimen of A. wushaensis was described in 2007, making Anshunsaurus the only thalattosaur with a known growth series other than Xinpusaurus. The pectoral and pelvic girdles are asymmetrical in this specimen, suggesting that the bones on the left and right sides of the animal did not ossify at the same rate while it was growing.[3] In 2007 a third species of Anshunsaurus, A. huangnihensis, was described from Xingyi. It is distinguished from the other two species on the basis of the shape of its coracoid, a bone of the pectoral girdle.
