Tremendous 122-foot titanosaur is unveiled at Museum of Natural History
A 122-foot-long cast of a titanosaur opens on Jan. 15. The massive exhibit was revealed to a packed house of media members Wednesday. The cast took six months to create and does not include any actual fossils, which are too heavy to mount. Instead, it is made of 3D prints made of fiberglass, based on 84 fossil bones that were excavated in Argentine Patagonia in 2014. The skeleton includes “missing” bones modeled after titanosaur’s close relatives.The species is so new that it has not been formally named by the scientists that discovered it, and is believed to be one of the biggest dinosaurs ever discovered.
