Marble Canyon fossil site
Cliffs in Marble Canyon, where a treasure trove of Cambrian fossils was discovered in 2012. The fossils are in the Burgess Shale, and rival the famed original Burgess Shale fossil site in diversity and preservation, according to the researchers who found the Marble Canyon locality. These cliffs are part of Canada's Kootenay National Park.
The fossil of a four-eyed arthropod called Leanchoilid from Canada's Marble Canyon, is also found in Cambrian-age rock in China.
