The 67 million-year-old dinosaur discovered near Faith, South Dakota, was named for Susan Hendrickson, who unearthed the giant creature. The hot question of whether dinosaurs were warm-blooded like birds and mammals or cold blooded like reptiles, fish and amphibians finally has a good answer.

The dinosaur, was named Dreadnoughtus schrani meaning 'fear of nothing'. It died between 66 million and 83 million years ago and still had not finished growing, reported Sydney Morning Herald.

A palaeontologist and an associate professor in College of Arts and Sciences in Drexel University, who led the excavation and discovered the fossil skeleton in southern Patagonia, Kenneth Lacovara, said that the species of dinosaurs, Dreadnoughtus schrani, was astoundingly huge. The creature was a titanosaur, a group of dinosaur that had several members who were the largest land animals on the Earth.

Dr. Lacovara said that the weight of the dinosaur was almost equal to a dozen African elephants or more than the weight of seven T-rex put together at 130,000 pounds.

The dinosaurs measured a length of eighty-five feet, had a thigh bone that had a height of less than two metres, tail was nine-metres in length and their neck was almost one metre in width. Suggestions were made that the dinosaur was muscular and powerful because the bones at the end of the tail had a large surface area that was made use of to attach muscles.

Dr. Lacovara exclaimed that they had a body that was the same size of a house, their weight was that of a herd of elephants and a weaponised tail that led to the dinosaurs not fearing anything. He thought that it was time the herbivores were given credit for being the toughest creatures in an environment.

Apart from the head, more than 70 per cent of the skeleton of the dinosaur were recovered so it is considered the most complete titanosaur discovered till date.

Dr. Lacovara said that this is the best example that they have of the most giant creatures that walked on Earth.

The biggest titanosaurs had remained a mystery as their fossils were incomplete, said a palaeontologist from the Carnegie Museum of Natural History, Matthew Lamanna.

The discovery was published in the journal, Scientific Reports.
