The world’s largest dinosaur that lived 100 million years ago, herbivorous Patagotitan mayorum, weighed 70 tons, its length up to 37 meters, height – 6, researchers found. The remains of six individuals, only about 200 bones were found in 2012 in Argentina. The results of the study reported in the journal Proceedings of the Royal Society B, says the website gazeta.ru.
Analysis of the bones showed that the individuals not reached its maximum size. The researchers suggest that they could die of thirst – perhaps together with other herbivorous dinosaurs Patagotitan mayorum came to drink to the lake, which dried up during periods of drought, and animals died from its shores. And dinosaurs are scavengers, eating the remains of dead animals, their bones trampled deep into the clay that contributed to the sound.
- In Argentina, the shepherd found the dinosaur eggs
Patagotitan mayorum, like some other discovered in Argentina the species belongs to the group of titanosaurs. In the Jurassic and Cretaceous periods titanosaurs lived on all continents except Antarctica.
Scientists are not yet able to say exactly what provoked the emergence of such giant species. They attributed this to the increase of plant diversity and, consequently, the expansion of the diet of herbivorous dinosaurs.
