The biggest shopping center in the Middle East Dubai Mall opened on Monday the permanent exposition of a 155 million-year-old dinosaur skeleton, dating from the late Jurassic Period.

The 24.4 meters long and 7.6 meters high adult dinosaur, found 90 percent intact, was unveiled to visitors for free on Monday night at the mall's Grand Atrium.

"Dubai Mall has brought it here to attract tourists and shoppers," said Sarah, one of the tourist guides who is explaining the brown-colored specimen to visitors.

The remains of the dinosaur, which has a long tail and slender neck, were discovered in 2008 at the Dana Quarry in Wyoming, the United States, and it's the first time ever that bones from one animal was found in a sleeping position.

It was previously displayed at the Houston Museum of Natural Science, and later bought by Dubai properties developer Emaar to permanently display in Dubai Mall. But the price for the skeleton was not disclosed.
