Brontosaurus returns!

The uncertainty of science: The popular but unofficial and rejected dinosaur name “Brontosaurus” has been resurrected by paleontologists.

A new study has found that the bones that had been assigned to Apatosaurus, the term that paleontologists in the 1970s chose over the more popular term Brontosaurus, actually appear to come from two distinct but different species, and they have chosen the more popular term for one of these species.

Brontosaurus was always easy to pronounce, which has probably contributed to its popularity as a general term for dinosaurs. When it was officially rejected in the 1970s there were a lot of unhappy fans of paleontology. I suspect the modern generation of scientists, children in the 1970s, had a warm spot in their heart for the term and have thus found a way to bring it back.
