The fine-grained shales that make up the Burgess were once part of the ancient landmass known as Laurentia, the ancient geologic core of the North American continent, and are home to some of the most diverse and well-preserved fossils in the world.

The sedimentary shales here contain fossils that open a window to marine life some 508 million years ago and include such weird and wonderful species like Anomalocaris and Hallucigenia.
