Paleontologists have found a dinosaur with the longest neck.

The dinosaur lived in East Asia more than 160 million years ago. An analysis of the bones and skull of the beast showed that the dinosaur known as Mamenchisaurus sinocanadorum had a neck 15 meters long. This is at least five times larger than that of a giraffe, whose neck is only 2-3 meters. Dinosaurs grew up to 50 meters in length and weighed over 70 tons. Despite the fact that only a few bones remained from the beast, the researchers were able to estimate its size by comparing it with other complete fossils. The long neck allowed sauropods to consume tons of food without spending a lot of energy on movement.
