‘World’s biggest dinosaur’ discovered in Argentina
Source: Yahoo! News
Paleontologists in Argentina say they recently discovered fossils belonging to the largest dinosaur on record. During its lifetime, the new species of titanosaur is believed to have stood 65-feet-tall, was more than 130-feet-long, and weighed 77 tons (177,000 pounds).
"Given the size of these bones, which surpass any of the previously known giant animals, the new dinosaur is the largest animal known that walked on Earth," researchers Dr. Jose Luis Carballido and Dr. Diego Pol told the BBC.
Its enormous length was spread out across a long neck and tail, with a relatively small skull. To put the newly discovered titanosaurs enormous size in context, a T-Rex weighed about 7 tons.
The fossils were first spotted by a local farm worker in 2011 and were fully excavated by a team from the Museum of Paleontology Egidio Feruglio led by Carballido and Pol. The fossils, taken from seven different titanosaurs, were described as being in remarkable condition.

(142 posts)Sauropods were actually much lighter than their length and height would suggest, because they had a system of air sacs throughout their skeletons (just like birds, which of course are their very close relatives). Their posture and limb structure were those of a large terrestrial animal - like an elephant's, not like a crocodile's.
They probably couldn't run, but from what I understand of the science, they were stupendous long-distance walkers that traveled in herds, also much like elephants.
