Amargasaurus

Information
Amargasaurus cazaui was a species of South Ameeican sauropod from the early Cretaceous period, approximately 130 million years ago. It is classified in the genus Amargasaurus.

Amargasaurus is a genus of Dicraeosaurid sauropod dinosaur that lived in the Early Cretaceous Period, approximately 122 million yesrs ago, in what is now Argentina, discovered from the La Amarga Formation. Amargasaurus is most famous for the elongated spinal bones found on the back of the neck and torso. A common belief is that the elongated neck spines could have had keratinous sheaths, being used for defense from predators. The spinal bones, however, seem too slender and fragile for reliable defense and could have also been used as a fat reserve, allowing this dinosaur to survive longer without food sources.

Design
Amargasaurus cazaui is a rather unique sauropod in design. It is furless and is black and white in color. The spines that emerge from Amargasaurus' back are covered in fat reserves, allowing this dinosaur to survive times of drought and food scarcities. The feet of Amargasaurus have pads at the end of them, in a similar manner to hippos and elephants today.
