Scientists have announced a giant dinosaur named Dreadnoughtus discovered in Argentina. The massive animal could potentially be the largest being to ever walk the earth, scientists argue.

According to the Associated Press, the massive dinosaur was discovered by Kenneth Lacovara of Drexel University in Philadelphia when he was conducting excavations in Argentina' southern province of Patagonia in 2005.

It weighed around 65 tons with a long neck and a tail measuring around 29 feet. Overall, the Dreadnoughtus measured 85 feet long and lived between 75 and 77 million years ago.

"What we can say with certainty is this is the biggest land animal that we can actually put a number on," Dr. Lacovara told the New York Times. The fossils he discovered almost a decade ago are the most complete of any other titanosaur, the group of large dinosaurs to which the Dreadnoughtus belongs.

Though the Argentinosaurus could potentially be the largest dinosaur ever with a vertebrae bone larger than that of the Dreadnoughtus, there are too few bones to accurately determine the beast's size. However, researchers discovered "more than 200 bones, representing 45 percent of the skeleton and 70 percent of the bones behind the head."

Dr. Lacovara discovered the fossils along with Matthew C. Lamanna from the Carnegie Museum of Natural History in Pittsburgh and Lucio M. Ibiricu of the Centro Nacional Patagonico in Argentina. It took the team of researchers four years to excavate all the fossils, which were then transported in 2009 to Drexel with Argentina's permission.

The Washington Post reports that researchers have ten academic papers on the Dreadnoughtus works, including four already written. An upcoming study will use 3D scans to analyze the movements of the giant dinosaur. Anyone can access the 3D scans for free.

Dreadnoughtus means "fearing nothing" and the beast's scientific name of Dreadnoughtus schrani, honors a World War One battleship and technology entrepreneur Adam Schran, who helped finance the research, according to the New York Times.
