This undated artist rendering provided by the Carnegie Museum of Natural History shows the Dreadnoughtus. The dinosaur Dreadnoughtus had a 37-foot-long neck, 30-foot tail, and weighed an estimated 65 tons. In life, Dreadnoughtus was an herbivore that likely spent much of its life eating massive quantities of plants to maintain its enormous body size.

Researchers studying the remains of an enormous dinosaur — a creature that was bigger than seven bull elephants — have given it an equally colossal name: Dreadnoughtus, or "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 four-legged beast, with a long neck and powerful 29-foot tail, stretched about 85 feet long and weighed about 65 tons. That's more than seven times the weight of even a plus-size male African elephant. (AP)
