Barosaurus was an amazingly large animal. When standing on its hind legs, this plant-eating beast would have been as tall as a five story building.
Barosaurus was discovered in the 1890s by one of the most famous American Paleontologists, Othniel Charles Marsh, in an area that would later become Dinosaur National Monument, Utah, North America.
Most of Barosaurus’ incredible length would have been made up of its neck and its tail. Probably only about one-fifth would have been its actual body. Imagine trying to lift and move that long of a neck. Fortunately for Barosaurus, its neck bones were hollow and very light, making this task easier. Its head would have been small and light as well.
