The dinosaur’s estimated body mass, based on a circumference equation utilizing the same bones, was 69 tons, which is about 10 tons less than the weight of the entire Space Shuttle. The animal, identified as a titanosaur, lived approximately 101.6 million years ago, according to Carballido and his team.
Titanosaurs were the last group of sauropods to evolve. These were four-legged, small-headed plant-eating dinosaurs with long necks and tails. They tended to be very large.

Argentina was home to several such dinosaurs, including Argentinosaurus and Puertasaurus. In the past, some of these dinosaurs were regarded as having been the world’s largest, but their bones were either smaller than those for Patagotitan, or there were not enough remains to permit proper size estimates.
The dinosaurs all lived in a lush, relatively warm environment.
“We have records in the same area of large conifer trees, flowering plants, ferns, and the remains of large carnivorous dinosaurs such as Tyrannotitan, as well as turtles, crocodiles, and primitive lizards,” co-author Diego Pol of MEF said. “So, this area probably had a temperate and humid climate, with meandering rivers.”
