T-Rex fossil flies to Netherlands through O'Hare

CHICAGO (WLS) -- A Tyrannosaurus Rex was the oldest passenger on a flight at O'Hare Tuesday to the Netherlands.

The fossilized remains of the T-Rex was loaded onto a KLM flight. The Dutch airline threw the 66 million-year-old specimen a party with cake and a dinosaur passport.

The bones were originally unearthed in Montana. Once it goes on display overseas, it will be the first T-Rex fossil displayed in a museum outside of North America.
