From June to July, Prof. Jin Jisuo from Western University and Prof. André Desrochers from the University of Ottawa, Canada paid a visit to NIGPAS. During their visit, they were invited to give lectures about “the post-extinction radiation of marine shelly benthos in the Silurian: Rising from ashes” and “the omission surfaces of palaeotropic carbonates from the Silurian Anticosti Island, Canada”. They also went to Guizhou and Hubei to study the Ordvician-Silurian carbonates in the field.
