Amargasaurus
South America · Cretaceous
Amargasaurus, from Argentina, had two rows of long spines on its neck. It was a sauropod: a big plant-eater that walked on four legs.
Did you know?
Scientists still debate what covered its spines.
Look together
Can you trace the long spines on its neck?
An idea to try
Count the spines with your finger, from the head to the back.
For the adult reading along
A little more to discover
Amargasaurus cazaui lived in the Early Cretaceous. The long paired spines arise from neck vertebrae, not the skull. A 2022 histological study supports tissues connecting these spines; the drawing shows one reconstruction with sails. Their exact outline remains interpreted.
