A new fossil discovery may unseat the largest dinosaur, the Argentinosaurus, as the largest known dinosaur, an uneasy feat when considering the Argentinosaurus dimensions. However, scientists in Argentina have confirmed the discovery and have begun excavating for the fossils.

Paleontologists began excavating for the fossils in the southern region of Patagonia, according to The Guardian. The 90-million-year-old fossils are the largest found, according to the scientists. One of the thigh bones unearthed is bigger than an adult human male, and its dimensions are outstanding. Scientists from the Museum of Paleontology Egidio Feruglio estimate the specimen to be around 130 feet long and around 80 tons heavy -- or the same weight as 14 African elephants.

"It's like two trucks with a trailer each, one in front of the other, and the weight of 14 elephants together," said José Luis Carballido, the Argentine paleontologist who led the dig. "This is a real paleontological treasure. There are plenty of remains and many were nearly intact, which is unusual."

According to BBC News, the scientists were alerted when farmers stumbled upon the fossils near La Flecha desert, some 135 miles west of Trelew, Patagonia.

"Given the size of these bones, which surpass any of the previously known giant animals, the new dinosaur is the largest animal known that walked on Earth," the researchers told BBC News. "Its length, from its head to the tip of its tail, was 40m. Standing with its neck up, it was about 20m high -- equal to a seven-story building."

Scientists ultimately uncovered 150 fossils belonging to seven specimens. This new type of sauropod is seven tons heavier than the Argentinosaurus, but like its predecessor, this newly discovered dinosaur was an herbivore. When the Argentinosaurus was first discovered, notes BBC News, its size was estimated from only a few bones.
