China shares fossil treasures with the world

China has been a rich source of fossils for nearly a century, beginning with the discovery of so-called Peking man (Sinanthropus pekinensis), known today as Homo erectus pekinensis in the mid 1920s. The first Chinese dinosaurs were described in 1929, the sauropod Helopus (now Euhelopus) and the ornithopod Tanius, described by the Swedish paleontologist Carl Wiman. Over the next six decades, further dinosaurs were described by Yang Zhongjian (C.C. Young) and his students Dong Zhi-Ming and Zhao Xijin, but remained poorly known in the West. A golden age of Chinese paleontology began as spectacular feathered dinosaurs were described from Lagerstätten in northeastern China beginning in 1996. Today, China has more genera of dinosaurs than any country on earth. In addition to dinosaurs and birds, China has among the oldest fossil vertebrates on earth with Cambrian fish such as Haikouella and Myllokunmingia, one of the first fossil flowers with Early Cretaceous Archaefructus, and a rich fauna of mammals, including Early Eocene Archicebus, one of the earliest known fossil primates. Fossil mammals range from a Jurassic beaver-tailed aquatic docodont, Castorocauda, to a Cretaceous gobiconodontid, Repenomamus, which had the nerve to munch on a baby dinosaur, to Ice Age elephants, woolly rhinoceros, horses, and saber-toothed cats. Surprising new fossils of all kinds will continue to be discovered in China for decades to come.
