caption_attribution_description: A hypothetical life restoration of Argentinosaurus huinculensis, a titanosaur from the Late Cretaceous of Argentina, pencil drawing, digital coloring • Based proportionally on skeletal reconstructions of Argentinosaurus by spinoinwonderland and randomdinos on DeviantArt&#91;1&#93;&#91;2&#93; and other titanosaur reconstructions found online. This image is somewhat hypothetical as Argentinosaurus isn't known from complete remains; some of the proportions shown here, such as the neck, tail, forelimb length, and skull shape, are not certain and could be subject to change should more fossil material be found. The missing parts are inspired primarily by the more complete Patagotitan. • Osteroderms are not yet known in Argentinosaurus. Osteoderms are known from at least 10 titanosaur genera spread across the family tree, including a relative Medozasaurus, but it's not clear if all titanosaurs had them.&#91;3&#93;&#91;4&#93; Titanosaur osteoderms are rare and their layout and position on the body are not certain. The position and layout of the osteoderms have been loosely based on this interpretation, which is based on the work of Vidal et al 2015.&#91;5&#93;&#91;6&#93; • The colours and patterns, as with the majority of all prehistoric animal reconstructions, are speculative.

context_page_description: Titanosaurs were a group of large sauropod dinosaurs. Together with the brachiosaurs and relatives they make up the larger clade Titanosauriformes.
  They were some of the heaviest creatures ever to walk the earth. Titanosaurs included Saltasaurus, Isisaurus, Argentinosaurus and Paralititan. The group includes the largest land animals known to have existed, such as Patagotitan – estimated at 37 m long with a weight of 69 tonnes – and the comparably sized Argentinosaurus and Puertasaurus from the same region. They were named after the mythological Titans of Ancient Greece.
  The titanosaurs were the last great group of sauropods before the Cretaceous–Paleogene extinction event. They were the dominant herbivores of their time. The fossil evidence suggests they replaced the other sauropods, like the diplodocids and the brachiosaurids, which died out between the Upper Jurassic and the mid-Cretaceous.
