Kalloprion Kilmisteri

Kalloprion kilmisteri, named after Lemmy Kilmister from Motorhead. Notice the scientific correct Lemmy-warts at the dorsal side of the worm.
Made for 10 Tons´ and Geomuseum Faxes exhibition "Heavy Metal and Punk Fossils".

This polychaete worm was described in 2006. The model is part of the 10TONS Exhibition Rock Fossils on Tour, as the species was named in honor of Ian Fraser “Lemmy” Kilmister (1945–2015), legendary founder, bass player, and singer of British heavy metal band Motörhead.

Although scolecodonts generally occur in great abundance in the Gotland rock succession (up to thousands of specimens per kilogram of rock), Kalloprion kilmisteri is quite rare. It is found in some of the oldest rocks exposed on the island and disappears during a short-lived, yet severe environmental and biotic crisis known as the Ireviken event, which wiped out several groups of organisms.
A similar (possibly the same) species reappears in younger, post-event, rocks and also in other regions in Baltoscandia, such as Estonia. Thus, either this species went extinct or; more likely, it temporarily disappeared and found refugia elsewhere, only to recolonize the area when the environmental conditions had improved. Eventually, it did go extinct but the reason is uncertain, which is why Motörhead’s “Killed by Death” can be considered as fitting as anything, at least until the contrary is proven. Apparently Lemmy was honered of having the polychaete named after him, however feeling a little old by lending his name to a fossil.
