Austroposeidon is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous Presidente Prudente Formation of Brazil. It has know one species, Austroposeidon magnificus (meaning "Magnificent Southern Poseidon"). It was a large sauropod in fact, the largest dinosaur discovered in Brazil. It is a titanosaur, and reached up to 25 meters long (82 feet). The specimen was discovered in the Campanian-Maastrichtian Presidente Prudente Formation of the Bauru Group by palaeontologist Llewellyn Ivor Price 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.
