Problem of the name of Brontosaurus

Paleontologist Marsh of the United States named Brontosaurus in a fossil of Sauropodomorpha form which he discovered in 1879. Paleontologist concluded, “the fossil specimen called Brontosaurus is the genus same as” [Apatosaurus announced excavation in 1877] as a result that American field natural history Museum investigated it again in 1903. Therefore it unified the generic names in “Apatosaurus” which the scientific name of “Brontosaurus” disappeared, and was named earlier, but generally people was rarely known, and the name of “Brontosaurus” was continued using for what was standardized with a public book and the illustrated book after it.

The name of “Brontosaurus” did not see it with the recent illustrated book, but thinks that there is the person with the attachment to “Brontosaurus” toward the age.
