Its fossils are about the size and shape of an empanada (6 inches, or 15 centimeters, long).-"It is the first new species reported from a stunning fossil find in Marble Canyon in British Columbia's Kootenay National Park. The Marble Canyon fossil beds, located in 2012, rival the iconic Burgess Shale for their diversity of soft-bodied fossils and exquisite preservation, scientists said."
