Rare Fossilized Predators Up for Auction at Sotheby's

Sotheby's is set to auction the fossilized skeletons of a Pteranodon and a Plesiosaur, two prehistoric predators, in New York. The Pteranodon, with a 20-foot wingspan, is expected to fetch upwards of $6 million, while the 11-foot-long Plesiosaur, believed to have lived about 190 million years ago, is estimated to sell for $600,000 to $800,000. These fossils are rare and well-preserved specimens, attracting comparisons to the Loch Ness monster. Sotheby's has not disclosed the identity of the seller.
