Susan Hendricson, a paleontologist who discovered the T. rex Sue near Hell Creek formation, where many T-Rex fossils have been found. Sue is the nickname given to FMNH PR 2081, which is one of the largest, most extensive, and best preserved Tyrannosaurus rex specimens ever found, at over 90 percent recovered by bulk. It was discovered on August 12, 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 until October 7, 2020 when T. rex Stan was auctioned for US$31.8 million. Sue is now a permanent feature at the Field Museum of Natural History in Chicago, Illinois. Photo by Ira Block
