Pollingeria grandis

Middle Cambrian
Burgess Shale, Stephens Formation
Field, British Columbia
Canada

Pollingeria is a genus of animal from the Burgess Shale that still resists identification over 100 years after its discovery. Walcott suggested they were the chaetae of a much larger wormlike animal. Other authors have suggested it is some kind of colonial organism, while others think each specimen is an individual animal. 8mm on 25mm slab
