Enormous species of Dinosaur that weighs nearly 60 tons discovered in Argentina

A group of researchers on 4 September 2014 announced that they have discovered fossilized remains of an enormous species of a long-necked, long-tailed dinosaur that weighs nearly 60 tons. This discovery is being considered as the largest terrestrial animal with a body mass that can be accurately determined.
 
The researchers have discovered the fossilized remains of the dinosaurs in the Patagonian hills of Argentina. The remains of the skeleton were unearthed between 2005 and 2009.

The giant herbivore has been dubbed as Dreadnoughtus Schrani by paleontologist Kenneth Lacovara at Drexel University in Philadelphia. Dreadnoughtus schrani is a reference to the armored battleship meaning fearing nothing and is also a tribute to the dinosaur's perceived fearlessness.

The team that studied the fossil remains of the species said that it died about 77 million years ago. They also claimed that at the time of its death it was in the process of growth. The giant herbivore belongs to a group known as tyrannosaurs that had enormous bodies and long necks.

Measurement of the fossilized bones from hind leg and foreleg revealed that the animal was 26 meters long and weighed 59.3 tons, which made it heavier than some Boeing 737 that is around 50 tons. The team of researchers has been able to calculate the body size of the species much accurately as they were able to collect 70 percent of bones of it, except for those in the head.

The group of researchers, including those at Drexel University in the US, the announcement in the British science magazine Scientific Reports.
