One of the most iconic dinosaurs, Brontosaurus, is back on its own in the dino history books, having regained its status as a unique genus and species.
The reclassification, addressed in a study appearing in the latest issue of the journal PeerJ, appears to resolve a long-standing debate over what to do with Brontosaurus, which looked a lot like the dinosaur Apatosaurus.
That similarity had caused paleontologists to rename Brontosaurus as Apatosaurus excelsus. In short, it was just considered to have been another type of Apatosaurus. Gone was the cool nameBrontosaurus, which means "thunder lizard" in Greek.
