Apatosaurus was an herbivorous diplodocidsauropod. There are three accepted species Apatosaurus ajax, Apatosaurus louisae, and Apatosaurusparvus. Brontosaurus execelcus was first though to be its own genus, than it was moved to Apatosaurus for a while, but paleontologists including Robert T. Bakker relized that several differences in the skull, means that Brontosaurus is once again a valid genus
An apatosaurus is a large sauropod dinosaur of the genus Apatosaurus, belonging to the late Jurassic period.
Othniel Charles Marsh discovered one species of Apatosaurus, and named it Apatosaurus ajax. When he discovered Apatosaurus excelsus, though, he assigned it to its own genus, Brontosaurus. Later it was found that both Brontosaurus and Apatosaurus ajax belonged to the same genus, so Brontosaurus was reassigned to Apatosaurus excelsus.

Brontosaurus is now called Apatosaurus excelsus. Apatosaurus excelsus is one of the four species in the genus Apatosaurus.

Brontosaurus was discovered two years after Apatosaurus ajax. It was assigned to its own genus, but it was later found that Brontosaurus belonged to the same genus as Apatosaurus ajax. Thus, the name Brontosaurus is invalid, and now it is called Apatosaurus excelsus.
The apatosaurus most likely ate the cycas plant. It is part of the cycad family.
A dinosaur named the Apatosaurus was discovered, documented, and named. Afterwards, another dinosaur was found, documented, and named the Brontosaurus. Years later, it was reaalized that the Brontosaurus was really an Apatosaurus, and it is not another genus.
Othniel Charles Marsh discovered a species of Apatosaurus in 1877, and he named it Apatosaurus ajax. Two years later, he discovered another species of Apatosaurus. Marsh didn't realize that they both belonged to the same genus, though, so he named the new species Brontosaurus excelsus. When it was determined that Brontosaurus excelsus was actually a species of Apatosaurus, its name was changed to Apatosaurus excelsus.
Brontosaurus was discovered by Othniel Charles Marsh in 1879. Two years before, however, he discovered Apatosaurus ajax. It turns out that Brontosaurus belonged to the same genus as Apatosaurus ajax, so the name Brontosaurus isn't valid. Brontosaurus is now called Apatosaurus excelsus.
