Meet Dreadnoughtus, Biggest Dinosaur Yet One in Patagonia weighed 65 tons, was still growing By John Johnson, Newser Staff Posted Sep 4, 2014 12:28 PM CDT 28 comments Comments An artist's rendering provided by the Carnegie Museum of Natural History shows the Dreadnoughtus. (AP Photo/Carnegie Museum of Natural History, Mark A. Klingler) (Newser) – Introducing the new king of the dinosaurs, at least in terms of size. Researchers in the Patagonia region of Argentina found a brute they've named Dreadnoughtus, and they're laying claim to it being the largest land animal whose size can be accurately measured—thanks mainly to the fact that they found 70% of a skeleton. Some highlights of the study in Scientific Reports. Dimensions: It was 85 feet long and weighed 130,000 pounds. Dreadnoughtus had a 37-foot-long neck that enabled the plant-eater to feast without having to move around much. Also: It was still growing when it died about 77 million years ago. Context: "To put [the dino's 65-ton size] in perspective, an African elephant is about five tons, T. rex is eight tons, Diplodocus is 18 tons, and a Boeing 737 is around 50 tons," says study author Kenneth Lacovara of Drexel University in the Washington Post. Demise: The big guy and a smaller companion got stuck in something akin to quicksand, which is why the bones are so well preserved. Name: Dreadnoughtus means "fear nothing." The full name is Dreadnoughtus schrani, with "schrani" an homage to tech entrepreneur Adam Schran, who helped fund the research, notes the New York Times. New king coming? Maybe. Researchers think a cousin in the titanosaur group named Argentinosaurus might have been bigger, reports Discovery. They just need to collect enough bones to prove it. Another recent study says a meteor strike's "bad timing" is to blame for dinosaurs' mass extinction.
