Something that has been a long time coming... As I have no air tools for prepping fossils, I got the bee in my bonnet to try using bits of wood and glue to break away bits of matrix partially covering leaves from McAbee specimens that I collected years ago (before the gov't ban on collecting there). It worked pretty well on these few pieces I tried. The only difficulty came when the matrix to be removed was too thick and integrated with the surrounding matrix. Then it would only peel the thinnest layer off the top. Another round or rounds could eventually accomplish the task in this case, as I did in one instance. Glue used was Lepage's gel-type superglue. I let them cure for a half a day to a day before pulling. Soaking the stick in a jar of acetone frees the broken-off piece if wanting to retain it (as I did with the Ginkgo below). This could work on any number of similar fossils from e.g. Green River, etc. but I can't guarantee consistent results!
