Just when you thought it was safe to get back in the dirt.
From The Washington Post:
Md. family uncovers 15-million-year-old shark skeleton during backyard dig
Donald Gibson found the first vertebra Oct. 23, just as he had begun to dig out the space for the sunroom he had promised to build in the back yard of his parents’ home in Calvert County.
Over the following week, his brother Shawn found another vertebra, and then another, and then a few more — each one about 18 inches deep into the ground. Soon, Shawn Gibson’s 7-year-old, Caleb, joined in on the digging. He’s at an age of being “thrilled to go out and not just play in the dirt, but actually find pieces,” Gibson said of his son.
After all, it’s not that unusual to dig up fossils in the Calvert Cliffs neighborhood. But then they found something more: a straight column of vertebrae, two feet long. And at the end, a tooth.
The digging stopped.
What the Gibsons unearthed were the remains of a 15-million-year-old snaggletooth shark, which paleontologists say is more complete than any other fossil of its kind in the world.
