The faunal analysis of trilobites is carried out on the levels of genus and family. As result, the Arctic region, Mongolian, Chichibu, Tethyan and the Burma-Thai-Malaysian geosynclines, the Yangtze basin and Australian, Arctic, western North American and South American regions are distinguished. Endemic genera of these regions are listed. The Silurian trilobites of Eastern Asia clarified that the Oriental Meterogen which consists of the Koreo-Chinese land, Yangtze basin and Indosinian Island was embraced by the Mongolian, Chichibu and Tethyan geosynclines from the Pacific side.
