About Austroposeidon
What it was like
Austroposeidon was a titanosaur, a long-necked plant eater. It is known from bones of the neck and back, and it was one of the largest dinosaurs found in Brazil.
Its world
It lived in the Late Cretaceous in what is now Brazil. Its bones come from the Presidente Prudente Formation. Its closest relatives include Futalognkosaurus and Mendozasaurus from Argentina.
How it was found
Bandeira and colleagues named it in 2016. Scans of the bones showed that they were filled with air spaces, which kept the huge skeleton light.
