Chengjiangocaris longiformis Hou and Bergström,1991 | |
Chengjiangocaris is an extinct genus of fuxianhuiid arthropod known from the Cambrian of South China. It contains two species, C. longiformis which was described in 1991. C. kunmingensis was described in 2013 by and colleagues.[1][2] One specimen of C. kunmingensis shows detailed evidence of a nervous system.[3]
