Websteroprion

Websteroprion ("Webster's saw") is a genus of eunicidan polychaete that lived during the middle Devonian period in what is now Canada.

[1] The genus was named after the bassist Alex Webster of the death metal band Cannibal Corpse.

If this is true, Websteroprion would use its large jaws to eat live prey, algae, and decaying matter.

However, the jaws of polychaetes do not necessarily designate specific feeding habits, so precise knowledge remains unknown without preserved gut content or soft tissue.

[1] All of the specimens of Websteroprion are of a similar large size, which may indicate juveniles and adults had differing environmental preferences and thus would not be preserved together.
