The fossil specimen was found in the Patagonia region of Argentina in 2005 and is thought to be between 75 and 77 million years old. According to the Washington Post, who broke the story yesterday, the remains were“remarkably complete and well-preserved for a titanosaur.”
While there was no skull found, the remains are about 70% complete, enabling the researchers to create computerized 3D reconstructions of the bones, and physical models to understand how the giant creature would have moved and functioned.
Presumably it wouldn’t have had to walk much, using the length of that 37-foot long neck to feed. Its only downfall (literally) would be falling over: Its ribs would most likely be crushed, unable to withstand 65 tons on top of them.
