"modified to accomodate new data, it's "on shaky ground." Damned if you do...."

If you can't tell if something is 560my or 580my, then everything is 6000 years old. lol

In 1976, according to the Australian Museum, these Burgess Shale fossils were dated at 515 million years old (middle Cambrian).

How is this 45 million year discrepancy being reconciled?

Where is the evidence for the new date of 560 million years?

What are all the implications of this new "dating"?

Is the Burgess Shale Cambrian, or not?
