We report the discovery of new fossils from the Ediacara Biota, a group that contains the oldest evidence of complex animal life. These fossils existed more than half a billion years ago, before the evolution of hard parts (shells, bones, etc). As such, abundant and diverse communities of the Ediacara Biota are known from just a handful of sites around the world, leaving many questions regarding their timing and distribution difficult to answer. Our new specimens were recovered from the Mackenzie Mountains, a remote mountain range on the western border of Northwest Territories, Canada, and provide novel insight into the evolution and proliferation of animal life on Earth.
