English: Originally known as Titanosaurus, Isisaurus is a genus of titanosaurian dinosaur from the Late Cretaceous of India and Pakistan. Its name was changed in honor of the Indian Statistical Institute, after the defining traits of the genus Titanosaurus became obsolete as more species were discovered. Isisaurus is known from better remains than many other titanosaurs that were known at the time of its description. Isisaurus was a medium-sized sauropod, measuring 18 m long and weighing 15 t. It had a short, vertically directed neck and long forelimbs.
