New massive dinosaur was 'largest creature to ever roam the Earth'

The name roughly translates to the "giant from Patagonia" - with a nod to the Mayo family, who own the farm where the fossils where found.

Paleontologists have unearthed a new species of titanosaur in Agentina's Patagonia.

"I don't think they were scary at all", explained Diego Pol of the Egidio Feruglio paleontology museum in Argentina and co-author of the research.

A cast of the dinosaur's skeleton is on display at the American Museum of National History in NY.

The bones of the largest known species of dinosaur was discovered during excavations in the South of Argentina.

Now, Scientists have officially named the species Patagotitan mayorum and have discovered that it belongs to a group of extra-large titanosaurs that lived around 100 million years ago.

Based on these proportions, the beast likely weighed about 76 tons - to put that into perspective, the Space Shuttle only weighed about 74.8 tons.

Those numbers make the Tyrannosaurus Rex and other meat-eaters "look like dwarfs when you put them against one of these giant titanosaurs", Pol said.

The museum celebrated the news on its social media accounts with a amusing video that showed texts between the dinosaur and another famous large tenant of the museum, the blue whale. Rather, given the margin of error surrounding such size estimates - especially estimates of other massive (but far less complete) sauropod skeletons - paleontologist Mathew Wedel argues the competition for World's Largest Dinosaur™ is closer to a "three-way tie" between Patagotitan and two other titanosaurs, Argentinosaurus and Puertasaurus.

The finding also suggests that they could be hanging around in groups, perhaps to look after young, says Roger Benson of the Britains University of Oxford. "They were probably massive big slow-moving animals".

"In one of the levels there is a femur that, clearly, had been stepped on by another animal", said researcher Jose Luis. Researchers believe that an explosion in the plant life at the time is what caused the animals to grow in size so quickly. Along with a forest, it was like an all-you-can-eat buffet for these dinosaurs and they just got bigger.
