About Argyrosaurus
What it was like
Argyrosaurus was a large titanosaur, a long-necked plant eater. It is known from a front leg, which shows it was a big, heavy animal.
Its world
It lived in the Late Cretaceous in what is now Argentina. Its bones come from the Lago Colhué Huapi Formation, where it shared the land with the titanosaur Aeolosaurus and the duckbill Secernosaurus.
How it was found
Lydekker named Argyrosaurus in 1893, making it one of the first dinosaurs named from Argentina. Its name refers to the country, whose name comes from the Latin word for silver.
