== Discovery and naming == thumb|Speculative life restoration Austroposeidon is known from a single specimen, MCT 1628-R, which consists of portions of the cervical (neck), dorsal (back), and sacral (hip) vertebrae (including a cervical rib and one complete dorsal vertebra). The specimen was discovered in the Campanian-Maastrichtian Presidente Prudente Formation of the Bauru Group by palaeontologist Llewellyn Ivor Price in an outcrop along the Raposo Tavares Road in 1953, but the remains were not described until 2016. The animal was likely preserved by a crevasse splay on a floodplain, judging by the fine sandstone that the specimen was found in. Unfortunately, the site where the specimen was recovered has now been lost to urban development after Felipe Medeiros Simbras was unable to locate the site.
