Behind the scenes
The scientific community considered Brontosaurus to be a fictional species for over a century, but a 2015 study concluded that Brontosaurus was a real species. Before then, all the fossils of it were falsely believed to be simply mistakenly identified Apatosaurus fossils. [1] However, the study has been contentious and the issue is considered open. [2] [3]
