The story of the word

Marsh named it in 1879 for the noise a body that size suggested. In 1903 Elmer Riggs argued the specimen belonged to the earlier-named Apatosaurus, and the rules of zoological naming gave the older name priority, so the better name lost while museums went on using it for most of a century. A 2015 study of sauropod anatomy made the case that Brontosaurus is a separate genus after all, and that argument has not closed.
