The biota of the Ediacaran period (635 - 541 ma) is of critical importance to our understanding of the origin of animals because it immediately precedes the Cambrian fauna, from which all subsequent animal life evolved. Localities of this age are justly famous for the exceptional quality of preservation of soft-bodied organisms. One of the best known and most important Ediacaran localities is at Mistaken Point, Newfoundland, Canada. We got to talk to Dr. Alex Liu, a research fellow at the University of Cambridge, about Mistaken Point, and the nature of its biota.
