Chicago’s Field Museum of Natural History is the home to SUE, a 67-million year-old Tyrannosaurus rex fossil discovered in 1990 by paleontologist Sue Hendrickson near Faith, South Dakota. It was purchased by the Field Museum at an auction in 1997 for $8.4 million. It took 30,000 hours to prepare the more than 250 bones and teeth in her skeleton.
