“Apex” — A Mounted Stegosaurus Skeleton
Apex, a stegosaurus skeleton discovered in Colorado in 2022 sold for $44.6 million at Sotheby’s in New York last night to become the most valuable fossil ever sold at auction. It was bought by Ken Griffin, the Citadel hedge fund founder. Measuring eleven feet tall and 27 feet long the fossil exceeded its pre-sale estimate of $4 – $6 million by more than eleven times at the Natural History auction. There were seven bidders in the hunt. Apex was discovered by professional fossil hunter Jason Cooper. He named it Apex because it would have been the most formidable predator in its environment. It is virtually complete, with 254 fossil bone elements (of an approximate total of 319), with additional 3D printed and sculpted elements. Evidence of arthritis indicate that it lived to an advanced age.
