吃：植物長脖子恐龍白堊紀晚期

Saltasaurus was a small sauropod with a short neck and stubby legs. It lived in Argentina during the Late Cretaceous, about 70 million years ago. It was one of the first sauropods known to have armor made of bony plates in its skin.1 2

趣味知識

Saltasaurus was the first sauropod found with armor. It had bony plates called osteoderms embedded in its skin, which was a surprise to scientists.1 2

The armor came in two types: larger oval plates up to 12 centimetres long, and tiny round or pentagonal ossicles about 7 millimetres across.1

Saltasaurus had a very wide belly, shaped a bit like a hippopotamus. Some scientists thought it might have lived in water.1

Fossil eggs found in Patagonia, Argentina, may belong to saltasaurines. The eggs were about 11 to 12 centimetres in diameter, and some contained embryos with skin impressions showing bead-like scales.1

Saltasaurus lived about 70 million years ago, near the end of the age of dinosaurs. It was one of the last sauropods before they went extinct.1 2

The vertebrae in Saltasaurus had shallow depressions called pleurocoels, which are also seen in other titanosaurs like Alamosaurus and Gondwanatitan.1

關於 Saltasaurus 最常被問的問題

?How big was Saltasaurus?

Scientists disagree on its size. One estimate says it was about 6 metres long, another says up to 8.5 metres (28 feet), and a third says up to 12.8 metres (42 feet). Its weight was probably between 2.5 and 7 tonnes.1 2

?What did Saltasaurus eat?

Saltasaurus was an herbivore, meaning it ate only plants.1 2

?Did Saltasaurus have armor?

Yes, it had bony plates called osteoderms embedded in its skin. There were larger oval plates up to 12 centimetres long and tiny round ossicles about 7 millimetres across.1 2

?Could Saltasaurus swim?

Some scientists think it might have lived in water because its wide belly looked like a hippopotamus, but nobody knows for sure.1

?When did Saltasaurus live?

Saltasaurus lived about 70 to 66 million years ago, during the Late Cretaceous period in what is now Argentina.1 2

?How did Saltasaurus lay eggs?

Fossil nests show that female saltasaurines dug holes with their back feet, laid clutches of about 25 eggs, and buried them under dirt and plants. The eggs were about 11 to 12 centimetres across.1

迷思破解王

迷思： All sauropods were huge and had no armor.

真相： Saltasaurus was relatively small for a sauropod and had armor made of bony plates, showing that some sauropods did have protection.1 2
