The dinosaur in the Crystal Hall of the Royal Ontario Museum was a herbivorous dinosaur. In order to reach the leaves, it grew such a long neck.
What makes it different from other dinosaurs is that it is a dinosaur from the southern hemisphere and was discovered in Argentina by a female archaeological student who participated in an excavation for the first time.
And this skeleton was completely printed with a 3D printer. Real dinosaur fossils are very heavy and difficult to stand up so high without a stand.
