he largest and best-preserved Tyrannosaurus Rex skeleton to date was discovered on this day in 1990.
The skeleton was nicknamed “Sue” after its discoverer, the paleontologist Susan “Sue” Hendrickson. In the meantime, the skeleton was sold for 7.6 million dollars, the highest price ever paid for a dinosaur skeleton.
Sue Hendrickson discovered the skeleton in South Dakota. Its great value stems from the fact that it is 80% complete. It is 12.9 meters long, and it is estimated that the Tyrannosaurus Rex to which it belonged weighed around 6.4 tons when it was alive.
Due to the nickname “Sue”, it is often referred to as a female’s skeleton, but the actual sex of the individual in question remains unknown. “She” lived around 67 million years ago, and died at the age of 28.
Today the skeleton is an exhibit in the famous Field Museum of Natural History in Chicago. The skeleton’s teeth are up to 30.5 centimeters long, and its huge skull weighs 272 kilograms.
