How did she get there? Who is Sue? This is what visitors see when they first visit Dino Sue at the Field Museum in Chicago How Was Sue Discovered? In the summer of 1990 Sue Hendrickson was hunting fossils in South Dakota A surprise was waiting for her One morning she climbed a cliff to get a better look at some huge bones she had spotted She had found the remains of a huge Tyrannosaurus rex, also called a T rex Sue Hendrickson was amazed to find a T rex The bones had been buried deep under rock and dirt Over millions of years the rock had worn away How Did Sue Become a Fossil? She died … Her bones were covered with sand and mud… The bones hardened into rock They were preserved Pressure turned them into fossils Hard Work Uncovering the bones was hard work A team of workers gathered at the location They used small tools and worked slowly It took them five days just to remove the 30 feet of rock that covered the bones The bones were old and weak Workers cut the fossils out of rock Workers had to be careful As each bone was found, it was cleaned Then it was labeled and packed Workers found almost every bone in the dinosaur’s body She was named Sue, after Sue Hendrickson Workers spent 25,000 hours working on Sue’s skeleton Boxes of Bones The Field Museum in Chicago bought Sue In 2000 more than 250 boxes of bones arrived there Museum workers spent two years putting Sue back together Each bone was cleaned again Sue’s skull makes her look like a fierce animal When they were done, the museum had a nearly complete skeleton of Sue The skull on Sue is made of plastic Her real skull is too heavy to be mounted on the body Sue’s real skull is in a smaller room in the museum In that room visitors can get a close-up view Sue Today Putting Sue together in the museum took time and money Was it worth it? Yes! Sue provided evidence for scientists She helped them prove facts about life millions of years ago She showed them how a T rex moved and how long it lived Sue may give clues that answer even more questions in the future Facts About Sue Scientific Name: Tyrannosaurus Rex Age: 67 million years Length: 42 feet (12.8 meters) Height: 13 feet (4.0 meters) Weight of Skull: 600 pounds (272 kg) Number of teeth: 58 10 Responding Word Builder Make a word web around the word fierce What other words mean the same as fierce?
