Since 2000, the regal presence of SUE has graced the main hall of Chicago's Field Museum. But anyone who's visited after February 5, 2018, will find Stanley Field Hall absent of the stately dinosaur. Why? SUE, the Field Museum's most famous dinosaur, is getting its own room!

SUE is the largest and best-preserved specimen of Tyrannosaurus rex ever discovered. But how big are the bones of this beast? With these stats, it's easy to see why the hall might seem so empty while SUE's gone:

• Length: 40.5 feet

• Height: 13 feet

• Skull: 600 pounds; so heavy that a replica is used on the skeleton. The actual skull had its own display case.

• Teeth: 58 total, each as long as a dagger

• The length of time it took to dismantle just the feet: 2 hours

What to expect when she returns in Spring 2019

• A new pose: SUE will be "walking rather than skulking," said associate curator of dinosaurs Pete Makovicky in a post on the museum's blog.

• Repositioned gastralia: Scientists suspect these rarely preserved bones acted as a sort of diaphragm to help SUE breathe.

• A less-svelte belly: to reflect growing research

• Visit SUE's replacement: The so-far-unnamed titanosaur will take residence in Stanley Field Hall in May 2018.

  • At 122 feet long, it's longer than two buses and three times as long as SUE.

  • It's so tall, it'll peek at visitors over the second-floor balcony.

  • Unlike SUE, visitors will be able to walk beneath it—and touch it!
