Anne-Marie Berger gets an up close look at Sue the T-Rex, a model of one of the most well-preserved tyrannosaurs rex fossils ever discovered. An exhibit from the Field Museum in Chicago, Sue is on display at the St. Louis Science Center through April 2009. The model, made from a mold of the actual bones, is 42 feet long and 12 feet high. When alive, Sue would have weighted over 7 tons. Sue, discovered in North Dakota by paleontologist Sue Hendrickson in 1990, has helped scientist gain much insight about T-Rex.
