Explanation:

[STC0017857]. A 72-foot-tall brachiosaurus skeleton may be seen inside Chicago O’Hare’s Terminal 1, Concourse B. The skeleton is on loan from the Field Museum of Natural History in Chicago, which had to relocate it in 1999 to make room for a brand-new, enormous Tyrannosaurus dubbed “Sue.” Dallas/Fort Worth International Airport also has a connection to dinosaurs because it was constructed on the site of the discovery of a Plesiosaur that lived 70 million years ago.
