Recently, Dr. PAN Bing, an assistant researcher in Professor ZHU Maoyan’s group at the Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences (NIGPAS), in collaboration with a team of researchers from China, the UK, and the USA led by Prof. Guo Junfeng (Chang'an University, China), conducted research on small shelly fossils from South China. Fortunately, among the numerous small shelly fossils from the Shuijingtuo Formation (c. 520 Ma), they discovered the earliest siphuncle-bearing cephalopod, Eoceras shaanxiense, and systematically analyzed 32 specimens of this new species. The scientific results were recently published in Nature.
