Sometimes, when you freeze/thaw Mazon Creek fossils they split more than just in half. Sometimes you get 3 or 4 pieces. Sometimes you get 47 larger ones (more than 1/4") and LOTS of tiny ones. You make the best lemonade you can with the lemons you've been given. Here's a "before" and "after" of one I repaired today. Unfortunately, too much of the surface detail crumbled into pinheads and powder. Would have been a real beauty if nature wasn't as cruel as it is.
