鄂西志留纪早期三叶虫Latiproetus Lu,1962的新材料

In the Early Silurian trilobite fauna of South China, the proetids, next to the encrinurids, are the second dominant group both in relative abundance and species diversity. They have important implications for biostratigraphy and palaeoecological and palaeogeographical reconstructions. Among these proetid trilobites, Latiproetus Lu, 1962 is the most common genus in the Lower Silurian of South China.
