Lyrarapax 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. Its fossilized remains were found in Yunnan in southwestern China. A second species was described in 2016, differing principally in the morphology of its great appendages.
