Buy Tickets

The world-famous fossil known as “Sue” is the largest, best-preserved, and most complete Tyrannosaurus Rex ever found. Sue measures 42 feet long from snout to tail and 13 feet tall at the hip. She boasts 58 dagger-like teeth and cuts a fine figure as the Museum’s most popular backdrop for visitor photos. A replica skull crowns the skeleton in Stanley Field Hall, while Sue’s original skull, which weighs 600 pounds, rests within an exhibition on the Museum’s balcony, under a mural depicting this majestic creature in the flesh.
