A fossilized dinosaur horn contained soft tissue. If the dinosaurs died off 65 million years ago, how did the tissue survive?
Another along the same line, this video from 60 minutes. It features the Mary Schweitzer that discovered the soft tissue in a dinosaur bone. (I think I had mentioned that the tissue was in a dinosaur horn, but that was a discovery by another paleontologist)
And another about Mary Schweitzer's work.
