Next stop, Jurassic Park

Cretaceous Park, actually:

A Tyrannosaurus rex fossil has yielded what appear to be the only preserved soft tissues ever recovered from a dinosaur. Taken from a 70-million-year-old thighbone, the structures look like the blood vessels, cells, and proteins involved in bone formation.

Most fossils preserve an organism's hard tissues, such as shell or bone. Finding preserved soft tissue is unheard of in a dinosaur-age specimen.
