Apatosaurus was a herbivorous sauropod dinosaur that lived in North America during the Late Jurassic period. Upon concluding their study, Tschopp's team suggested that, due to a number of physical differences, the original Apatosaurus and Brontosaurus could be classified as different genera, and so the Brontosaurus was resurrected. Diplodocus is longer, thinner, and has lower back with not as much of an arch. Although the type species, B. excelsus, had long been considered a species of the closely related Apatosaurus, researchers proposed in 2015 that Brontosaurus is a genus separate from Apatosaurus and that it contains three species: B. excelsus, B. yahnahpin, and B. parvus.Brontosaurus had a long, thin neck and a small head adapted for a .
