Frickin' cool. Maybe we can make that Lost World theme park after all.

"Paleontologists have discovered [a href="http://www.sciencenews.org/articles/20050326/fob1.asp"]soft tissue inside the fossilized thigh bone of a T-Rex[/a]. The tissue included blood vessels, bone cells, and perhaps even blood cells." From the article: "When paleontologists find fossilized dinosaur bones during a dig, they usually do everything in their power to protect them, using tools like toothbrushes to carefully unearth the bones without inflicting any damage.
However, when scientists found a massive Tyrannosaurus rex thigh bone in a remote region of Montana a few months ago, they were forced to break the bone in two in order to fit it into the transport helicopter. This act of necessity revealed a startling surprise: soft tissue that had seemingly resisted fossilization still existed inside the bone. This tissue... was so well preserved that it was still stretchy and flexible."
