Ottoia: Fossil evidence of paleoecology

The Burgess shale, which preserved soft body parts, has many Ottoia fossils. And not only are soft structures preserved. On the left is a fossil Ottoia which preserves the three haplophrentis the worm ate before it was swept to its death.

In the painting, Ottoia is shown looming over these hapless critters.
