Lyrarapax unguispinus is an anomalocaridid that lived in the early Cambrian period 520 million years ago. Its neural tissue indicates that the anomalocaridid great appendage is pre-protocerebral, resolving parts of the arthropod head problem.[1] Its fossilized remains were found in Yunnan in southwestern China.[2]
