Sue the Tyrannosaurus has plenty of room to wander around inside the cavernous spaces of the Field Museum, the third member of the Museum campus. Sue is the largest and most complete Tyrannosaurus Rex ever discovered, and the cause of a considerable amount of controversy - found in 1990 in South Dakota, the legal battle for ownership took five years to resolve and it wasn't until 1997 that the Field Museum made the winning auction bid of $8.4 million and brought Sue to Chicago. Now she gets to stare all day at the delicious but unsuspecting morsels who turn their back on her, while she enjoys the company of Egyptian mummies, Maya artifacts, stuffed animals and meteorites.
