On this day in 1990, fossil hunter Susan Hendrickson discovers three huge bones sticking out of a cliff near Faith, South Dakota. The bones turned out to be part of the largest Tyrannosaurus rex skeleton ever discovered, a 65 million-year-old specimen dubbed Sue, after its discoverer.
Amazingly, Sue’s skeleton was over 90 percent complete, and the bones were extremely well-preserved. Sue’s skeleton went on display at the Field Museum in May 2000. The giant T-Rex skeleton, which is 13 feet high at the hips and 42 feet long from head to toe, is displayed at the Field Museum of Natural History in Chicago, Illinois. Another exhibit gives viewers a close-up view of Sue’s five foot-long, 2,000-pound skull with its 58 teeth, some as long as a human forearm.
Sue’s extraordinarily well-preserved bones have allowed scientists to determine many things about the life of T-Rex. They have determined that the carnivorous dinosaur had an incredible sense of smell and since Sue was the first T.rex skeleton to be discovered with a wishbone, scientists have support for their theory that birds are a type of living dinosaur.
