Paleontologist Sue Hendrickson discovered a complete Tyrannosaurus Rex skeleton to date in 1990. The skeleton was found in South Dakota and soon garnered the nickname Tyrannosaurus Sue after the scientist who found the remains. The fossilized skeleton of Tyrannosaurus Sue is now housed in the Field Museum in Chicago Illinois.
This fossil was auctioned off in October of 1997 and went for 7.6 million dollars. This is the most money that any dinosaur skeleton was ever been bought for. Tyrannosaurus Sue is so valuable because it is so complete. Over 90 percent of the hulking bulk of the Tyrannosaurus Rex’s skeleton was recovered by Sue Hendrickson.
