Scientists discover fossilized remains of massive dinosaur

NEW YORK (KGO) -- The fossilized remains of a dinosaur that weighs more than a Boeing 737 have been discovered. Researchers have given it an equally colossal name: Dreadnoughtus, which means "fearing nothing."

Scientists hope its unusually well-preserved bones will help reveal secrets about some of the largest animals ever to walk the Earth.

The massive creature was unearthed in the Patagonia region of Argentina. When the four-legged beast roamed the earth, it stretched about 85 feet long and weighed about 65 tons.

That's seven times bigger than a T-Rex and more than seven times the weight of even a plus-size male African elephant. It probably lived about 75 million to 77 million years ago.

Dreadnoughtus is named after the impervious early 20th century battleships.

This is the first of its species and it's most complete fossil ever found of any member of the gargantuan dinosaur group known as titanosaur.

Scientists say the herbivore could have done little other than eat to support its massive frame.

The creature is described in a study released by the journal Scientific Reports.
