| Abstract: | The research area includes the Liaodong Peninsula and the Huolianzhai area of the Taizihe Valley. The Middle Cambrian Hsuchuangian trilobite fauna comprises 45 species belonging to 23 genera and 2 subgenera, among which 5 species are new. Seven successive trilobite zones are recognized on the measured sections of the Hsuchuang Formation in the Liaodong Peninsula. These are as fllows in descending order.Hsuchuangian7. Bailiella- Lioaparia Zone6. Poriagraulos Zone5. Inauyops Zone4. Sunaspis Zone3. Pagetia jinnanensis Zone2. Daminoaspis Zone1. Hsuchuangia ZoneThe Middle Cambrian Hsuchuangian trilobite faunas of eastern Liaoning, characterized by the presence of Soleuoparia (Plesiolenoparia), Eotaitzuia, Zongtiaoshanaspis, Proasaphiscina, Squarrosoel-la, Plesigangdeeria, Damiaoaspis and Parawuania, indicate a close affinity with those of the Zhongtiao mountains of southern Shanxi and the Hsuchou area of northern Jiangsu. |
