On October 6, 2020, an anonymous buyer paid an astounding $27.5 million ($31.8 million with fees and costs) to own Stan, one of the world's largest and most complete Tyrannosaurus Rex (T. rex) skeletons. The price far surpasses the previous record holder, Sue — the largest and most complete T. rex skeleton — which was auctioned to Chicago's Field Museum of Natural History for $8.36 million in 1997.
