Question: are apatosaurus and brontosaurus the same?
Answer: Apatosaurus Used to Be Known as Brontosaurus In 1877, the eminent paleontologist Othniel C. Marsh bestowed the name Apatosaurus on a new breed of sauropod recently discovered in the American west--and two years later, he did the same for a second fossil specimen, which he dubbed Brontosaurus.
