 And finally for you, a T-Rex dinosaur skeleton is being dethroned. A Stegosaurus skeleton that's 150 million years old was sold for a record $44.6 million at Sotheby's. It was the most ever paid for a fossil, surpassing the almost $32 million paid for a T-Rex called Stan four years ago. This bidding war lasted 15 minutes with seven bidders from around the world on the phone.
