Temnospondyl amphibians from the Jurassic of the Southern Junggar Basin (NW China)

For the first time, remains of post-Triassic temnosponyls are described from the southern Junggar Basin (NW China). Middle Jurassic material from the uppermost part of the Toutunhe Formation consists of several isolated but well preserved skull bones and intercentra from all regions of the body that can be attributed to a brachyopid. The material in part shares important autapomorphies withGobiops desertus Shishkin, 1991, from the Upper Jurassic of Outer Mongolia, and is consequently referred to this taxon, partially with reservation. This represents the first record of this genus from China. It also yields new anatomical data and permits an emended diagnosis.Ferganobatrachus from the Middle Jurassic of Kirghisia is probably, as also shown by the new material, congeneric withGobiops. Two fragmentary specimens from the lower part of the Upper Jurassic Qigu Formation are tentatively referred to the Brachyopoidea because of features of the skull, mandible and vertebral column. They probably both represent a single taxon that was larger and more massively built thanGobiops desertus but closely related to this form.
