Aragosaurus (meaning "Aragon lizard") was a genus of sauropod dinosaur from the Early Cretaceous period of Galve, province of Teruel, in the autonomous territory of Aragón, Spain.[1] It was deposited in the Villar del Arzobispo Formation.

Aragosaurus was a large, quadrupedal plant-eating (herbivorous) dinosaur, which lived during the early Berriasian, about 145-140 million years ago.[2] It was about 18 metres (59 ft) in length and about 25 tonnes in weight.[3]

Like other sauropods, it had a long neck, a long powerful tail, a small head and a bulky body. It was broadly similar to Camarasaurus. It is represented by a partial skeleton, which was found in Spain and was named by Sanz, Buscalioni, Casanovi and Santafe in 1987. The type species is A. ischiaticus. Like Camarasaurus, Aragosaurus probably had a short, compact skull and a moderately long neck. The teeth were large and wide, and would have been useful for slicing through the leaves and branches of tall conifer trees. The forelimbs were only a little shorter than the hind limbs, and the tail was long and muscular.
