Arthropod, Burgess Shale. Lagerstatten.

Canadaspis is a genus of marine arthropod that has been considered an early crustacean or perhaps something even more primitive. It is known from the Early to Middle Cambrian of Canada, the western U.S. (Utah, Nevada), and China.

This interesting double comes from an old collection of Burgess Shale specimens. A veritable yin and yang of the ancient world.
