DNA has always been such a fascinating topic to me. In school, we had such a limited look into it and yet it seemed to be the thing in what makes us "us". I really hope as a society we continue to push the boundaries of our knowledge to see what DNA can tell us. And out of teeth? That is just so awesome.

For others who are having trouble understating the title, it basically translates as: "Set of proteins in bit of tooth from very old rhino from Georgia (the Caucuses) enables genetic classification of some related species."

DNA doesn’t survive that long. In this case they recovered the sequence of amino acids in proteins from the now-extinct rhino. Of course, the proteins were originally transcribed from the now-lost DNA, so you can use this information to infer this species position in the tree of life.
