Scientists can observe giraffes moving their long necks easily in all directions, but that is not possible for dinosaurs. By comparing vertebrae of young and adult specimens of Spinophorosaurus and giraffes using software, they believe the dinosaur, like the giraffe, had a large range of motion – both vertically and horizontally. Necks are also part of giraffes’ mating rituals, and some think it may be the reason for their long necks.
