Myoscolex is an early animal known from the Cambrian Emu Bay Shale in South Australia. It is of unknown affinity but has been interpreted as an annelid and as an arthropod close to Opabinia. Myoscolex is the earliest known example of phosphotized muscle tissue, and as to which shows distinct annulation.

Myoscolex ateles was named by Glaessner in 1979.
