Prompt used to create the image
Scientifically accurate paleoart of Dreadnoughtus, a herbivore Titanosauria dinosaur from the Campanian to Maastrichtian ages of the Late Cretaceous (about 76–70 million years ago). A huge sauropod about 26 meters long with a broad, wide body. Reference: Dreadnoughtus is a genus of titanosaurian sauropod dinosaur containing a single species, Dreadnoughtus schrani. It is known from two partial skeletons discovered in Upper Cretaceous rocks of the Cerro Fortaleza Formation in Santa Cruz Province, Argentina. It is one of the largest terrestrial vertebrates known from reasonably complete remains, with the immature type specimen measuring 26 metres (85 ft) in total body length and weighing up to 48–49 metric tons. 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 Late Cretaceous temperate floodplain in southern Patagonia, Argentina, like the Cerro Fortaleza Formation, with 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.

Dreadnoughtus
Name meaning: Meaning "fears nothing", after the armoured battleships of the early 20th century.

Pin Dreadnoughtus on the globe
Dreadnoughtus was a giant titanosaur from Late Cretaceous Argentina, so big that hardly any predator would have dared attack a full-grown one.
Fun facts
- Its fossils are among the most complete skeletons of any giant titanosaur, so its size can be estimated more reliably than that of giants known from only a few bones.
- The individual found was still growing, so adults may have been bigger still.
Who lived alongside it
Dinosaurs found in the same rock formation as Dreadnoughtus (Cerro Fortaleza), so they lived in the same region at roughly the same time.
