It's a fossil at this point, Lynne. It is stone and minerals, itself, no longer bone. It's in a creek bed so has probably been exposed by water erosion over the last few hundred thousand years. No viable DNA will be found, it's completely transformed after this much time. What makes it remarkable is the fact that it's a new species, and a complete specimen. Usually the bones become scattered after decomposition of the softer tissues, either from predator action or the weather and ground erosion. Complete specimens are very rare.
