Colossal dinosaur displayed in NY

37-meter skeleton offers visitors a surprise greeting when the elevator doors open

A cast and fossils from a brand new species of titanosaur, one of the largest dinosaurs ever discovered, went on display on Thursday in New York for the first time.

It comes from a species so newly discovered that its scientific name has not yet been formally released, said the paleontologists who made the extraordinary find in 2014, in Argentina's Patagonia region.
