Although if you are not familiar with all the various types of dinosaurs, for sure you will know 'T.Rex'. Probably you remember the iconographic scene from Steven Spielberg's 'Jurassic Park', when the people in the Jeep were chased by a T.Rex running wild. This kind of dinosaur really is kind of impressive. And especially the specimen we are talking about with an overall length of more than 12 meters and a skull of the size of 1.5 meters.
It was during the summer of 1990, when a group of workers from the Black Hills Institute searched for fossils at the Cheyenne River Indian Reservation, in western South Dakota near the city of Faith. By the end of the summer, the group had discovered Edmontosaurus bones and was ready to leave. However, before the group could depart, on August 12, a tire on their truck was deflated. While the rest of the group went into town to repair the truck, Sue Hendrickson decided to explore the nearby cliffs that the group had not investigated. As she was walking along the base of a cliff, she discovered some small pieces of bone. She looked above her to see where the bones had originated, and observed larger bones protruding from the wall of the cliff.
President of the Black Hills Institute, Peter Larson determined that the bones were from a T. Rex. A closer examination of the site showed many visible bones above the ground and some articulated vertebrae. The crew began to uncover the bones and was really excited, as it became evident that much of the dinosaur had been preserved. Previously discovered T. Rex skeletons were usually missing more than half of their bones. It was later ascertained that Sue - named after her discoverer Sue Hendrickson - was a record 80 percent complete. The large size and the excellent condition of the bones were also surprising. The skull was nearly 1.5 meters long, and most of the teeth were still intact.
Soon after the remains were found, a dispute arose over who was the legal owner of the bones. Originally, the Black Hills Institute had obtained permission from the owner of the land, Maurice Williams, to excavate and remove the skeleton, and had paid Williams $5,000 for the remains. After a lengthy trial, the court decreed that Maurice Williams retained ownership, and the remains were returned in 1995. Williams then decided to sell the remains, and contracted with Sotheby's to auction the property. On October 4, 1997, the auction began at $500,000; less than ten minutes later, The Chicago Field Museum had purchased the remains with the highest bid of $8,362,500, where the mounted bones are on display now. Only Sue's real skull was not incorporated into the mount as subsequent study would be difficult with the head 4 meters off the ground.
