Burgess shale dating
Your access to the NCBI website at gov has been temporarily blocked due to a possible misuse/abuse situation involving your site.This is not an indication of a security issue such as a virus or attack.Many and varied forms of complex multi-celled life suddenly sprang into existence without any trace of less complex predecessors.There are numerous single-celled forms at lower stratigraphic levels, but these offer scant help in solving the mystery.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.
Evolution's desperate attempt to fill this gap with more simple ancestral fossils has added more injury.
Around 708 million years ago (during the Late Pre-Cambrian) the supercontinent of Rodinia formed around the equator.
This was followed by the Cambrian Explosion (542 million years ago) when most major animal life forms evolved.
Transitional fossils have never been found as predicted by evolution.
From all we can tell, transitional missing links are imaginary, necessary only to support the evolutionary model.
Does this find contribute to understanding invertebrate evolution as it is claimed to have occurred?
