Aragosaurus

Aragosaurus is a genus of sauropod dinosaur that lived during the Early Cretaceous Period, about 130-125 million years ago. It was a large, herbivorous dinosaur, with an estimated length of about 49-66 feet and a weight of about 10-15 tons. Aragosaurus had a long, slender neck and a small head with a beak and small, peg-like teeth. It also had a long, whip-like tail, which it may have used as a weapon to defend itself against predators. Its body was probably covered in a layer of tough, scaly skin.

Aragosaurus was discovered in Spain in the 1980s and 1990s, and was named by paleontologists in 1992. It is considered a relatively primitive sauropod, and is thought to be closely related to other early sauropods such as Barapasaurus and Euhelopus. Aragosaurus is known from a number of well-preserved fossil specimens, including several partial skeletons and skulls, which have helped paleontologists learn more about the anatomy and behavior of this dinosaur.
