Ottoia is a stem-group archaeopriapulid worm known from Cambrian fossils.[3] Although priapulid-like worms from various Cambrian deposits are often referred to Ottoia on spurious grounds, the only clear Ottoia macrofossils come from the Burgess Shale of British Columbia, which was deposited 508 million years ago.[1] Microfossils extend the record of Ottoia throughout the Western Canada Sedimentary Basin, from the mid- to late- Cambrian.[1] A few fossil finds are also known from China.[4]
