Mistaken Point Ecological Reserve
The fossils are in Mistaken Point's tilted and faulted mudstone and sandstone. They are exposed, visible on the surface. They are part of the Ediacaran biota, the oldest complex (multicellular) life forms. The Ediacaran is the last period in the Proterozoic eon. They date to 579 to 542 million years ago, when all life was in the sea.
