The American and Argentine scientists have discovered a new species of dinosaur, which was the largest of the known. The lizard, named Patagotitan mayorum, reached a length of 37 meters, and its weight was 69 tons. He lived in the Cretaceous period 100 million years ago. About the discovery reported in the article, published in the journal Proceedings of the Royal Society B.
The remains of the animal, including fossilized vertebrae and ribs, was found in the southern part of Argentina on the territory of Patagonia. According to the researchers, the dinosaur belongs to the sauropods — the large group of four-legged herbivorous dinosaurs with long necks. In addition, Patagotitan mayorum is a titanosaur — an especially large representative of the sauropods. Previously, the giant dinosaur was considered to be another titanosaur — Argentinosaurus.
In July 2017, a group of paleontologists from Italy and France found in Madagascar the remains of a large reptile Razanandrongobe sakalavae that lived 165 million years ago. Reptile was a relative of crocodiles hunted dinosaurs and could even cope with a predatory lizard.
In the spring of 2017 paleontologists from the University of Queensland in Brisbane, Australia reported the discovery of the largest known dinosaur footprints. The footprint of an ancient being reaches 1.75 meters in length.
