Scientifically accurate paleoart of Argentinosaurus, a herbivore Titanosauria dinosaur from Albian times (110.1–106.3 million years ago). An enormous sauropod about 35 meters long, one of the largest land animals ever, with a broad, wide body. Reference: Argentinosaurus is a genus of giant sauropod dinosaur that lived during the Early Cretaceous period in what is now Argentina. Although it is only known from fragmentary remains, Argentinosaurus was one of the largest known land animals of all time, measuring 30–35 m (98–115 ft) long and weighing 65–80 t. It was a member of Titanosauria, the dominant group of sauropods during the Cretaceous. Anatomy: a long neck held roughly horizontal or slightly raised; pillar-like legs; front feet are columns without claws. Full body in side view, whole animal visible, standing in a Cretaceous floodplain in Patagonia, Argentina, with tall Araucaria conifers and ferns, no grass. Natural history museum illustration style, realistic textures and natural daylight, muted natural colors. No text, no labels, no humans, no modern objects.
