Mamenchisaurus sinocanadorum: The Dinosaur with the Longest Neck on Record
Paleontologists have discovered the remains of a dinosaur, Mamenchisaurus sinocanadorum, in northwest China that had a neck eight times as long as a giraffe's, making it the "longest-known neck in the animal kingdom." The sauropod had a 50-foot-long neck, about 10 feet longer than a typical bus, and its vertebrae were largely hollow, with 69% to 77% made up of "empty space." The long neck allowed sauropods to eat vegetation out of reach of other dinosaurs while conserving energy by remaining in one spot.
