Scientifically accurate paleoart of Barosaurus, a herbivore Diplodocidae dinosaur from about 157.9–143.1 million years ago. A very long neck held roughly horizontal, extending forward rather than straight up. An extremely long, whip-like tail held off the ground. Reference: Barosaurus is a genus of large sauropod dinosaur that lived in present-day North America during the Late Jurassic period. It was described by American paleontologist Othniel Charles Marsh in 1890. The genus contains a single valid species, B. lentus, though the African species B. africanus has since been assigned to Tornieria. B. lentus' holotype (name-bearing) specimen initially consisted of four caudal (tail) vertebrae that were found in 1889 in South Dakota by Ms. Anatomy: pillar-like legs with the front legs slightly shorter than the hind legs, front feet with a single thumb claw; a slender body and a long, low head. Full body in side view, whole animal visible, standing in a semi-arid Late Jurassic floodplain like the Morrison Formation of western North America, with conifers, cycads, ginkgoes, tree ferns and ferns along a river, no grass and no flowering plants. Natural history museum illustration style, realistic textures and natural daylight, muted natural colors. No text, no labels, no humans, no modern objects.
