Unfortunately at the time of the genus description the only fossils of Austroposeidon that we have are some vertebrae. However, comparison to other similar dinosaurs has led to realistic size estimates for this dinosaur of about twenty-five metres in length. Although not the biggest dinosaur, this does make Austroposeidon at the time of its 2016 description, the biggest dinosaur ever known to live in what is now Brazil.
