Anomalocaris, Wiwaxia, Hallucigenia, Opabinia, Waptia, and Marella

  

Burgess Shale - found in Canadian Rocky Mountains - "The Burgess Shale contains the best record we have of Cambrian animal fossils. The locality reveals the presence of creatures originating from the Cambrian explosion, an evolutionary burst of animal origins dating 545 to 525 million years ago. During this period, life was restricted to the world's oceans. The land was barren, uninhabited, and subject to erosion; these geologic conditions led to mudslides, where sediment periodically rolled into the seas and buried marine organisms" (http://www.ucmp.berkeley.edu/cambrian/burgess.html)
