This is a little different from the typical casting supplies that paleontologists work with, in that it is meant for eating and is incredibly easy to use. Select or make the item you would like to mold, mix equal qualities of blue and white, and smoosh the mixture all over the item for about an hour. Boom. Silicon molds.
Initially Meaghan had grand plans of using the new 3D printer at University of Oregon to print out mini replicas, but they have some daft rule about "academic intentions" and she couldn't figure out how to bullshit her way through it. Instead Meaghan made small sculpey clay replicas of an oreodont skull, and a flat medallion of a Dunkleosteus head, and a flat giant ground sloth. She also grabbed a bear skull that was just lying around (long story).
