Uragasaurus is a sauropod dinosaur, and the first mamenchisaurid known from Thailand. Mamenchisaurids exhibit the basic sauropod body plan, processing their herbivorous diet in their large gut. Uniquely, mamenchisaurid necks, like that of Uragasaurus, are proportionately long, even by sauropod standards.
