Preparation of fossil vertebrates, backboned
animals, is a very very meticulous process, it's one which we bring these specimens
back to the laboratory, often times we don't even know how good they are we get
them back here, but then our technicians take and they open the packages, and then depending on how hard the matrix is, basically the dirt or the rocks,
surrounding the bones, they take different strategies. I mean it can go all the way from just using a very fine brush or a small dental pick, to using things
that are like small sand blasters or small jackhammers to be able to extricate the
fossils from the matrix that they're preserved in.
