In a new study published in
Scientific Reports ("Earth's Oldest 'Bobbit Worm' – Gigantism In A Devonian Eunicidan Polychaete") by
Mats E. Eriksson of Lund University, Sweden,
Luke A. Parry of Bristol University, U.K., and
David M. Rudkin of Royal Ontario Museum, Canada, an extraordinary new species of polychaetes (bristle worms; the marine relatives of leeches and earthworms) is described from Canada. The new species,
Websteroprion Armstrongi, has a unique morphology and possessed the largest jaws recorded from the entire fossil record, reaching over one centimetre in length while usually being in the mm-size range. Investigation of the relationship between body and jaw size suggests that this animal achieved a body length in excess of a meter, which is comparable to that of extant "giant eunicid" species, colloquially referred to as "Bobbit worms" (the colloquial name is bizarrely enough derived from the infamous "
Lorena and
John Wayne Bobbit story." Don't know it? Well, Google it!). Gigantism in animals is an alluring and ecologically important trait, usually associated with advantages and competitive dominance. It is, however, a poorly understood phenomenon among marine worms and has never before been demonstrated in deep time based on fossil material. The new species demonstrates a unique case of polychaete gigantism in the Palaeozoic, some 400 million years ago. As suggested by
Rudkin, the species epithet honors
Derek K. Armstrong, who collected the material in 1994. The new genus name, Websteroprion, however honors
Alex Webster; bass player of death metal pioneers
CANNIBAL CORPSE. The study was headed by paleontology
Professor Eriksson, who also happens to be a "metalhead," and has previously named fossil species after both
Lemmy Kilmister and
King Diamond. Along those same lines, second author PhD student
Parry recently named a muscular fossil polychaete after
Henry Rollins. Being die-hard fans of
Webster's extraordinary bass playing technique and the music of
CANNIBAL CORPSE,
Eriksson and
Parry found it suitable to honor
Webster with this extinct monster worm. In the article, the authors explain the name by stating that it is "named after
Alex Webster — a 'giant' of a bass player — combined with 'prion' meaning saw". They also conclude that this primordial marine giant must have been fierce and creepy looking, which fits well with the amusingly graphic lyrics of
Webster's band.
