Burgess Shale priapulid worm

Reconstruction of the priapulid worm, Ottoia prolifica, from the Middle Cambrian Burgess Shale of British Columbia. This is the most abundant priapulid in the Burgess Shale, with hundreds of fossils recovered. Over thirty specimens show the hyolith, Haplophrentis, in the gut (one with six in a single individual). This indicates that, like modern priapulid worms, Ottoia was a voracious carnivore. Ottoia lived in u-shaped burrows in the sediment with a long proboscis extended for feeding. Sizes range from 2 to 16 cm. in length.
