Title: Barosaurus Category: Dinosaurs: Herbivores Time Period: Late Jurassic Heavy Lizard At up to 89 ft, (27 m ) long, Barosaurus had a strong resemblance to Diplodocus, but with one important difference. One third of this creature's length was made up by its amazingly long neck. Barosaurus had the same number of neck vertebrae as Diplodocus (fifteen), but each was remarkably stretched to create an astounding reach. Strangely, while diplodocid necks were longer than those of other sauropods, their forelimbs were shorter. If these giants grazed only on all fours, this would have limited their reach, but if they could rear on their hind legs, then reduced weight on the front of the body would have been an advantage. Barosaurus is therefore one of the best rguments for this kind of behavior - at full stretch,a rearing Barosaurus could hold its head 49 ft (15 m ) above the ground.
