BUENOS AIRES, May 17, 2014 (AFP) – Paleontologists in Argentina’s remote Patagonia region have discovered fossils of what may be the largest dinosaur ever, amid a vast cache of fossils that could shed light on prehistoric life. Finding so many individual dinosaurs at one site could confirm the hypothesis that these herbivores lived in herds, as well as determine any predators they may have had, whether they were scavengers, when they died and in what type of environment they lived, the paleontologist added. The creature is believed to be a new species of Titanosaur, a long-necked, long-tailed sauropod that walked on four legs and lived some 90 million years ago in the Cretaceous Period.
Researchers say the plant-eating dinosaur weighed the equivalent of more than 14 African elephants, or about 100 tonnes, and stretched up to 40 meters (130 feet) in length.
The previous record holder, also in Argentina, the Argentinosaurus, was estimated to measure 36.6 meters long.
A fossilized femur of the Titanosaur was larger than a paleontologist who lay next to it.
And the find didn’t stop there.
Bones from at least seven individual dinosaurs, including some believed to be younger, were found at the site.
