Gigantic Fossil May Belong to Biggest Dinosaur Ever
Paleontologists have discovered the fossil remains of a “titanosaur” in Argentina, which they say may belong to the largest dinosaur ever. And while they’ve only discovered a few bones so far, there’s no doubt they’re from a behemoth. One that likely measured more than 120 feet from head to tail, and weighed an earthshaking 220,000 pounds.
