The last minutes of the dinosaurs: Scientists say fossil find of charred bones shows something ‘strange’ was going on

Hundreds of fossil fragments scatter the dirt at excavation sites in Patagonia, revealing the mass graves of duck-billed dinosaurs.

The find is a part of a years-long study, in which researchers set out to excavate and analyse fossil remains from the base of South American to the northern tip of Antarctica.

Doing this will help scientists better understand the changing conditions as the continents began to form millions of years ago.

The researchers uncovered more than four miles of hadrosaur bones, including parts of the rib cage, femur, and vertebrae, according to Scientific American.

These dinosaurs were duck-billed herbivores, and are so far the southernmost dinosaurs found in South America.

'Something big happened here,' Marcelo Leppe, a paleobotanist and chief scientist at the Chilean Antarctic Institute (Inach) told Scientific American.

'There were thousands of animals whose bones are partially burned; perhaps they were victims of a paleo-wildfire. It's somewhat strange.'

After all they are discovering new ones like the one near Naples in Italy so it stands to reason there should be even older ones that have yet to be discovered.

Geologically, the Paleozoic starts shortly after the breakup of a supercontinent called Pannotia. Throughout the early Paleozoic, the Earth's landmass was broken up into a substantial number of continents. Towards the end of the era, the continents gathered together into a supercontinent called Pangaea, which included most of the Earth's land area. (Wiki)

S. America and Africa were right next to each other back then. Antarctica and Australia were both farther south at that time.

Pangaea was already breaking apart by the late Triassic, 200 million years ago. At this time, dinosaurs were just starting to dominate global ecosystems.

By the time the Cretaceous came to an end 65 million years ago, the continents were already taking their familiar shape we see today:
