The bone clearly belonged to a sauropod—a long-necked dinosaur like Brontosaurus, Diplodocus, and Brachiosaurus. Specifically, it was one of the titanosaurs—the last-surviving group of sauropods, and likely the biggest of them. But even known titanosaurs didn’t have thighs that big.
Is titanosaur bigger than blue whale?
Based on the size of the largest thigh bones, the scientists calculated that the titanosaur weighed around 170,000 pounds and measured 130 feet long and 65 feet tall. Though the ocean mammal is shorter by about 30 feet, the largest blue whales are estimated to weigh as much as 320,000 pounds.
