From May 2014:

Based on the length and circumference of the dinosaur's femur (thigh bone), the crew calculated the animal weighed 77 metric tons, seven more than the previous largest dinosaur record holder, the Argentinosaurus. The creature would have been roughly 130 feet long and 65 feet tall and is believed to have been a species titanosaur — an enormous herbivore dating from the Late Cretaceous period (about 100 to 60 million years ago) notable for their small heads, long necks and long tails. The team believes this creature likely lived in the forests of Patagonia between 95 and 100 million years ago, based on the age of the rocks in which its bones were found.

"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," the researchers told BBC News.
