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: Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks, burrows, cast-off parts, fossilised feces, palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science.
