Brontosaurus
Brontosaurus (; meaning "thunder lizard" from Greek , "thunder" and , "lizard") is a genus of gigantic quadruped sauropod dinosaurs. 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.
