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?
Yes, and the fossil being discussed is middle Cambrian. The moving of the date is pure speculation of a hypothesized precursor to the mollusk. As I stated in my other posts, this is just another "just-so" story.
