Good morning, I'm Steve Inskeep. Betty LeMaster watched a television program in Smyrna, Tennessee - a show about geology - and it got Ms. LeMaster wondering about the 10-pound rock she'd used as a doorstop for years.
She took it to Middle Tennessee State University and according to the Daily News Journal, testing revealed her doorstop is fossilized coral 450 million years old. Older than the dinosaurs, and still holds the door just fine.
