Sue, the largest, most complete and best-preserved Tyrannosaurus rex ever unearthed, gets to show off its new lair this week at the Field Museum in Chicago.
The museum on Friday will unveil the 40½-foot-long (12.3-meter) Sue, one of the world's best-known dinosaur fossils, in the giant meat-eater's new permanent exhibition space after 10 months of work moving and remounting the huge bones. Sue's bones were mounted in a way that reflects new understanding about the species acquired over the past two decades.
One major change was the addition of gastralia, bones resembling an additional set of ribs spanning the belly that may have provided structural support to help the dinosaur breathe.
