What is the biggest fossil?
Sue (dinosaur)
Sue is the nickname given to FMNH PR 2081, which is the largest, most extensive and best preserved "Tyrannosaurus rex" specimen ever found, at over 90% recovered by bulk. It was discovered in August 1990, by Sue Hendrickson, an explorer and fossil collector, and was named after her. After ownership disputes were settled, the fossil was auctioned in October 1997, for US $8.3 million, the highest amount ever paid for a dinosaur fossil, and is now a permanent feature at the Field Museum of Natural History in Chicago, Illinois.
