Unique Argentina Dino

Sometime around 2012, an Argentina rancher found an old bone sticking up out of the dirt. Intrigued, he scratched around, trying to dig it up, then contacted paleontologists at the local museum to come see what he had.

He had found some big bones. And when the paleontologists dug around, they discovered the remains of 6 of the biggest titanosaurs ever discovered.

Titanosaurs lived about 100 million years ago, on all the continents, including Antarctica, which was not covered in snow and ice, and may or may not have been located at the south pole at the time. The ‘Titans’ were herbivores. The most complete skeleton was for a young adult some 122 feet long (its neck was 39 feet) and weighing 70 tons (about the same weight as 10 modern African elephants). One of the femurs uncovered was 8 feet long; long enough to be a living room sofa, if it were more comfortable to sit on. How big would it have gotten when it was fully grown? How did it get that big? And what kind of creature - if any - could consider one of these dinner?

As I stated, there were (at least) 6 individuals found at this dig site, which at the time these Titans died, would have been the flood plain of a river. ALL of them were young adults. But they didn’t die as one group; there were at least 3 separate events that took lives, which may have been a few years to centuries apart. A theory is that the youngsters got separated from their herd and died from stress and hunger.
