On today's episode we're revisiting Mistaken Point, Newfoundland, Canada. At this lagerstätte it is possible to find large bedding planes full of Precambrian organisms called rangeomorphs. These are an enigmatic group, which still can't be placed on the 'tree of life'.

We are joined by Dr Emily Mitchell of the University of Cambridge, who's recent paper in Nature was able to show that you don't need to be able to fully understand the anatomy of an organism to discern some of its most intricate details.
