The length of four long buses, Titanosaur, is one of the largest dinosaurs ever discovered. An eight foot thigh bone of the dinosaur was discovered on a farm in southern Argentina back in the spring of 2014. Now it is on display in New York but it was not an easy installation as as Diego Pol -- the Argentinian Paleontologist who led the excavation -- explained.
