They’re made by a molecule-by-molecule replacement of the actual bones with silica or other natural elements and they wind up having the same form as the dinosaur bone. This is the way fossils are generally created, so it occurred to me that if I make a copy of a dinosaur bone, it’s really just a copy of a copy."
