Is the Prince Albert Crater in Canada a Mesozoic or Paleozoic Impact?

This is the Prince Albert Impact Crater.  It was found two years ago, but new information has reevaluated some of the initial results.  Originally, it was thought to be between 150 to 130 million years old.  This has now been broadened to 350 to 130 million years old.  That's...interesting.  Flickr gallery.
