Brontosaurus

A very confusing genus of dinosaurs. Why? Because people first thought the Brontosaurus was a separate genus and species. Then for decades people debunked the dinosaur as just another species of Apatosaurus, but now research yet again proves the existence of Brontosaurus.

So YES, the brontosaurus DOES exist (circa 2015).

People in the early 20th century: The Brontosaurus exists!
People in the late 20th century: There's no such thing as Brontosaurus, it's just a trendy term for the dinosaur Apatosaurus.

People after 2015: Now hold your horses, recent research shows the Brontosaurus actually DOES exist.
