Large theropod teeth found from the Upper Cretaceous of Jiangxi, Southern China
Large carnivorous dinosaurs, are common in the Late Cretaceous of Asia, but only some fragment teeth have been recovered from southern China. In a paper published in the latest issue of Vertebrata PalAsiatica, Dr. XU Xing, Institute of Vertebrate Paleontology and Paleoanthropology (IVPP), Chinese Academy of Sciences, and MO Jinyou, Natural History Museum of Guangxi in Nanning reported two isolated, large predatory theropod teeth from the Upper Cretaceous of southern China; the smaller tooth is assigned to a tyrannosaurid, whereas the larger one is greatly distinct from other known Late Cretaceous theropods, probably represents a previously unrecognized large predatory dinosaur. These large predatory theropod teeth were discovered for the first time from the Upper Cretaceous Nanxiong Formation of Jiangxi, helping better understand the known diversity of vertebrates from the Upper Cretaceous Nanxiong Formation, southern China.
