Amargasaurus is a genus of large sauropod dinosaur that lived in what is now Argentina during the Early Cretaceous period, approximately 120 to 100 million years ago. It was one of the earliest members of the sauropod group, and was among the first genera to have a neck composed of more than four vertebrae.
Amargasaurus was a quadrupedal herbivore, and its long, slender neck allowed it to browse from the tops of tall trees. Its long tail was used for balance while moving, and it had a small head with long, narrow jaws and peg-like teeth. The most distinguishing feature of Amargasaurus was the two rows of long spines running down its back. These spines were probably used as a defense mechanism against predators or to regulate body temperature.
Amargasaurus was about 9 meters (30 feet) long and weighed about 4.5 tons. It was a relatively small sauropod, and its remains have been found in the La Amarga Formation in the Ischigualasto-Villa Union Basin of Argentina. It was first described in 1991 by José Bonaparte and colleagues.

Amargasaurus were herbivorous dinosaurs, so they did not hunt other animals. However, they had certain techniques that they used to forage for food.
Amargasaurus had a long, narrow neck and small head, which allowed them to reach high into the trees and shrubs to eat the leaves and fruits that were available at the tops of the plants. These dinosaurs also used their long necks and heads to reach into crevices and cracks in rocks, where they could find insects and other small animals to eat.
They also had long, powerful legs that allowed them to move quickly and easily over the terrain, enabling them to search for food in a wider range of areas.
Amargasaurus also had strong jaws, which allowed them to strip off bark and other tough material and access the nutritious food beneath. This would have been especially useful in times when food was scarce and other resources were difficult to access.
Amargasaurus is an extinct genus of sauropod dinosaur from the Early Cretaceous Period of what is now South America. It was one of the earliest and most primitive members of the Diplodocidae, a family of large, long-necked, four-legged, herbivorous dinosaurs.
Amargasaurus was a relatively small sauropod, measuring up to 9 meters (30 feet) in length and weighing approximately 5 tonnes. Its most distinctive features were two rows of tall spines running down the length of its neck and back. It also had a small head and a long, whip-like tail.
The exact purpose of these spines is unclear. Some scientists believe they may have been used for display, or to help keep the animal cool. Others suggest that they may have been used for protection from predators.
Amargasaurusis known from fossilized remains found in the La Amarga Formation of Argentina, dating to the early Cretaceous period, about 125 million years ago. It was one of the first sauropods to be formally named and described, and the remains of several individuals have been discovered.
