Burgess shale dating

The vast array of complex life that appears in the lowest (or oldest) stratigraphic layer of rock, with no apparent ancestors, goes hard against evolutionary dogma.Evolution's desperate attempt to fill this gap with more simple ancestral fossils has added more injury.In 1940, fossils of amazing clarity and diversity were found in Canada's Burgess Shale.The extremely fine-grained shale preserved intricate details of previously unknown invertebrates.It takes a unique combination of factors relating to sediment deposition to create fossils and especially rare circumstances for them to preserve for millions of years.The Burgess Shale is one of the oldest examples of soft tissue preservation in the world.

Yet the Cambrian Explosion of Life has revealed life's complexity from the start, giving evolution a black eye.What it certainly did not do was reveal any of the transitional forms so desperately needed.This Burgess Shale is in the middle Cambrian, only slightly "after," or stratigraphically above, that representing the Cambrian Explosion.How can evolutionary scientists use the fossils as evidence of a common descent of all life?Certainly if the transitional forms had been found, they would be paraded for all to see.
