"Anomalocaris canadensis" Anomalocaris is the largest animal to be discovered in the Burgess Shale at 60cm.It was a formidable predator and used spiny grasping limbs to seize prey. On the under part of the head there is a mouth consisting of sharp teeth that could break tough animal exoskeletons. The lateral lobes along the length of its body provided a mechanism to allow the creature to swim. Complete fossils of Anomalocaris are rarely found.   Pencil and carbon dust on paper
