Amargasaurus

O nome significa: “lizard of La Amarga”1
Comía: PlantasPescozos longosCretáceo Inferior

Amargasaurus was a sauropod with a very unusual back. It had long, sharp spines sticking up from its neck and back, like a row of spikes. Scientists think these spikes might have been used for defense or to impress other Amargasaurus.1

Datos curiosos

1

Amargasaurus had very long, sharp spines on its neck and back vertebrae. These spines were much longer than those of its relative Dicraeosaurus.1

2

The spines on its neck were so long that they probably stuck out like a sail or a row of spikes. Scientists think they could have been used for defense or to show off to other Amargasaurus.1

3

Amargasaurus was a dicraeosaurid, a family of sauropods with shorter necks than other long-necked dinosaurs. Its closest relatives include Dicraeosaurus and Bajadasaurus.6

4

The only known skeleton of Amargasaurus is mostly complete. It includes the back of the skull, most of the backbone, and parts of the legs and hips.1

5

Amargasaurus lived about 125 to 121 million years ago, during the Early Cretaceous period. That is about 15 to 20 million years after its African relative Dicraeosaurus.61

6

Scientists think Amargasaurus could not rear up on its hind legs like some other sauropods. Its legs were built for slow, steady walking, not speed.1
