Silly brontosaurus, you shouldn’t be on this site! You’re not even real!
Due to the “Bone Wars” between 19th century paleontologists, Edward Drinker Cope and Othniel Charles Marsh, the brontosaurus was a mislabeled adult-version of an apatosaurus. On top of this, the skull attributed to the brontosaurus was, in fact, from another sauropod called the camarasaurus and mounted on the adult apatosaurus’ body. Originally, the brontosaurus was also thought to thrive in swamps, but no “brontosaurus” bones had ever been located near a body of water. Now, brontosaurus has become a synonym for apatosaurus.
