Sue T. Rex is the largest, best preserved and most complete Tyrannosaurus rex ever discovered. Only 21 other T. rex skeletons have been found, and those were less than 60 percent complete. Sue T. rex is more than 90 percent complete and extremely well preserved making it one of the most important fossil finds ever. Sue T. rex is named after the founder, Sue Hendrikson, a fossil finder. She stumbled upon Sue in 1990 at the Cheyenne River Indian Reservation near Faith, South Dakota, while waiting for a flat tire to be fixed. In 1997, the Field Museum purchased Sue T. rex with the generous financial support of McDonald's Corporation, Walt Disney World Resort, the California State university system, and private individuals. With their continued support, these bones are being prepared for exhibition in Chicago at The Field Museum in May 2000. Two 45-foot-long replicas of Sue will travel around the nation visiting 16 cities.
