A new thalattosaurian skeleton from the Upper Triassic Wayao Member of the Falang Formation, Guanling area, Guizhou Province, China can be referred to Miodentosaurus brevis. This new specimen provides a full knowledge of the osteology of the thalattosaurian, especially the anatomy of the pectoral girdle and both the fore- and hind-limbs. The presence of a few teeth restricted to the anterior ends of both the upper and lower jaws and dorsoventrally flattened ungual phalanges indicate that M. brevis is not a pure carnivore. With new information, some individual variations are recognized and the digital formula (2-3-4-5-5) of the pes can be identified as one of the diagnostic features for the thalattosaurian.
