Monrovian's Dinosaur Bone Featured on National Geographic

She didn't win $10,000, but she did finally find out what dinosaur the giant fossil her father found decades ago came from.

president Janie Duncan brought the bone to the National Geographic show "America's Lost Treasures" for appraisal and found out that the huge fossil is a femur from a stegosaurus.

A palenontologist on the show, which aired Wednesday night, said the bone was about 150 million years old from the late Jurassic period.

"That's my favorite dinosaur," Duncan said on the show.

The condition of the bone was unfortunately not museum quality, but the show's host told Duncan that it will continue to make a great family heirloom.

"Seventy-three years of waiting and you guys have given me this information, which is just priceless," she said.
