Symmorium is an extinct genus of stethacanthid shark.

 Symmorium is very similar in size and appearance to Stethacanthus, but is missing the spine with brush on its back. Some scientists think that Symmorium is actually a female Stethacanthus, while other scientists think Symmorium is a different group of shark, separate from Stethacanthus.
