Guangweicaris spinatus: A redescription of an Early Cambrian Fuxianhuiid Arthropod from the Guanshan Biotaod southwest China.
[sciencythoughts.blogspot.com]
The Early Arthropod Guangweicaris spinatus was described from specimens collected from the mudstones of the lower Wulongqing Formation in 2007. It is a member of the Fuxianhuiidae, a of stem- Arthropods (i.e. Arthropods that are not descended from the earliest common ancestor of all living Arthropod groups) otherwise known only from the Chengjiang Biota. As such this species can potentially shed a great deal of light on the nature of the earliest Arthropods, although, despite there being a large of specimens available, it has recieved relatively little attention to date.
