Aysheaia feeding on sponges. Illustration of Aysheaia, a caterpillar-shaped soft-bodied animal, feeding on sponges. This animal is known from fossils in the Burgess Shale site (508 million years old) in British Columbia, Canada. The Burgess Shale fossil site records a key moment in Earth's history, the Cambrian Explosion, when an unprecedented period of evolution produced a wide diversity of body types, including those of today's animals. | |
