Andesaurus (/ˌændᵻˈsɔːrəs/ AN-də-SAWR-əs; "Andes lizard") is a genus of basal titanosaurian sauropod dinosaur which existed during the middle of the Cretaceous Period in South America. Like most sauropods, it would have had a small head on the end of a long neck and an equally long tail. Andesaurus was a very large animal, as were many others of its relatives, which included the largest animals ever to walk the Earth.
In 1991, paleontologists Jorge Orlando Calvo and José Fernando Bonaparte named Andesaurus, which refers to the Andes Mountains and also includes the Greek word sauros ("lizard"), because of the proximity of this animal's remains to the Andes. Andesaurus fossils were found by Alejandro Delgado, after whom the single known species (A. delgadoi) is named.
