Paleontologists have discovered several partial skeletons of a previously unknown species of dinosaur in northwestern China, according to a study published in the journal Nature Communications.

A team led by Xing Xu, from the Institute of Vertebrate Paleontology & Paleoanthropology at the Chinese Academy of Sciences, Beijing, excavated the fossils, dating them to around 174 million years ago during the Middle Jurassic period (174 to 163 million years ago).
