Tianzhenosaurus (Tianzhen + Greek sauros="lizard") is a genus of ankylosaurid dinosaur discovered in Tianzhen County, at Kangdailiang near Zhaojiagou Village, in Shanxi Province, China, in the Late Cretaceous Huiquanpu Formation. Thus far, a virtually complete skull and postcranial skeleton have been assigned to the genus, which is monotypic (T. youngi Pang & Cheng, 1998).
This was a medium-sized ankylosaurian, the skull measuring 28 centimetres (11 in) in length, with a total body length of approximately 4 metres (13 ft).
Some authors have suggested that Tianzhenosaurus is actually a junior synonym of Saichania chulsanensis, but this matter remains unresolved, and Vickaryous et al. (2004) placed it within the Ankylosauridae, nested as the sister group to Pinacosaurus.
