摘要
Amongst new specimens collected from the upper part of the Telychian Xiushan Formation of Llandovery (Lower Silurian), at Wanmin Town in Yongshun County, western Hunan Province, nearly all are assigned to Coronocephalus gaoluoensis Wu. More than twenty are whole and articulated specimens, thus providing a sound basis for the study presented here. The cephalon of this trilobite is very peculiar. The present Coronocephalus gaoluoensis, in terms of its pattern of facial suture, is almost identical with Coronocephalus rex and Senticucullus. They may all be assigned to a distinctive subfamily of Encrinuridae.
