By studying the fossilized bones of these giant plant-eaters, as well as the internal anatomy of modern dinosaur relatives, scientists have created a life-size model of the Mamenchisaurus that served as the centerpiece for this fascinating exhibition. Although this 60-foot-long female was not the largest sauropod, Mamenchisaurus is known for its extremely long neck, which accounts for fully half its body size! On one side, bumpy, knobby scales make up the animal’s simulated skin — giving guests a realistic idea of how this and other sauropods may have looked. On the other side, a virtual dissection and a video projected on the animal’s midsection show how its organs and body systems supported the colossal size of these sauropods.
The World’s Largest Dinosaurs included specimens of sauropod vertebrae, a giant femur, skin impressions and many other fossil finds. It also offered plenty of opportunities for hands-on discovery, including a hand pump that demonstrates how much pressure would have been needed to circulate blood through a sauropod’s long neck to its head, and a simulated fossil dig at the end of the exhibition.Each of these fossil finds illuminated how Mamenchisaurus and other super-sized sauropods thrived on Earth for approximately 140 million years.
The World’s Largest Dinosaurs is organized by the American Museum of Natural History, New York, in collaboration with Coolture Marketing, Bogotá, Colombia.
