‘Apex’ Stegosaurus Skeleton Becomes the Most Expensive Fossil Ever Sold at Auction


A stegosaurus skeleton nicknamed “Apex” has broken the world record to become the most expensive fossil ever sold after being put up for sale at Southeby’s high-stakes Natural History Auction earlier this week.

The skeleton that served as the crown jewel of the July 17 New York auction earlier this week was billed as the largest and most complete stegosaurus ever to be found, and put up for sale. The armored dinosaur had been left undisturbed for around 150 million years prior to its discovery by fossil hunter Jason Cooper, who made the find after clocking an enormous femur bone and dorsal plates sticking out of the ground during a May 2022 birthday walk on his private ranch in Moffat County, Colorado.

It took Cooper and his team two full Summers to excavate the rocky site, but in the end, their labours paid off, with the ground yeilding 254 of the roughly 319 bones that make up a complete adult stegosaurus.
