About Antarctosaurus
What it was like
Antarctosaurus was a titanosaur, one of the long-necked plant eaters that ruled the southern continents late in the age of dinosaurs. It may have been about 18 meters (59 feet) long. Its lower jaw was square at the front, a sign that it cropped plants in wide mouthfuls close to the ground.
Its world
It lived in the Late Cretaceous. Its best bones come from Argentina, including the Anacleto Formation. Other bones from Brazil, Uruguay and India have been linked to it, but many scientists doubt that they belong to the same animal.
How it was found
Huene named Antarctosaurus. Its name refers to the south, not to Antarctica. The original bones may not all come from one animal, and several extra species named later are now doubted, so much about this dinosaur is still uncertain.
