'''''Apatosaurus''''' (Greek: ἀπατηλός ''apatelos'', and σαῦρος ''sauros''; "deceptive lizard") refers to three species of [[dinosaur]] originally discovered in the 1870s in the western United States. In 1903, a similar dinosaur named ''Brontosaurus'' was thought to have been the same species as ''Apatosaurus'' and was thus called Apatosaurus for over a century. Recent studies show, however, that both were actually separate species all along; ''Apatosaurus'' had a lower and wider neck than ''Brontosaurus''.<ref>https://www.scientificamerican.com/article/the-brontosaurus-is-back1/</ref>
