Pollingeria grandis

Field, British Columbia

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. Five specimens, 10mm, 10mm, 14mm, 14mm, 14mm on 61mm x 52mm slab
