It's been ten years since Sue -- the Field Museum's Tyrannosaurus rex--arrived at the Chicago museum.
To celebrate the anniversary of the 67-million-year-old's time in Chicago, the museum is holding a number of events, including a premier of a new 3-D movie about Sue, the Associated Press reports.
On Wednesday, Field Museum Collections manager Bill Simpson cleaned Sue to prepare her for all the attention she'll receive in the next few weeks. Hopefully, she's not shy.
