A farmworker in Argentina’s Patagonia region came across some extraordinarily huge dinosaur bones. Then in 2013 scientists from Museum of Paleontology Egidio Feruglio in Trelew began work on the site, which is about 135 miles from the city. And what they found is totally mind blowing.
In fact, Patagonia has long been a rich source of fossilized dinosaur bones. One creature found there in the past is the huge Argentinosaurus, one of a family of oversized dinosaurs called the titanosaurs. These titanosaurs were sauropods, herbivorous beasts with extremely long necks and tails, and disproportionately small heads. The Diplodocus and the Brontosaurus were both sauropods, for example.
The Argentinosaurus, which lived around 95 million years ago, was discovered by an Argentinean rancher in 1987. The man found a leg bone that was so big he thought it was a fossilized tree trunk. He also uncovered a single vertebrae as large as an adult human being.
