The DS has had more games about cleaning dinosaur fossils than we ever imagined: Dinosaur King, Fossil Fighters and the upcoming Fossil Fighters: Champions to name three. Now, to get you really excited, Nintendo has released a video showing exactly how to clean fossils in its upcoming DS adventure.

The trailer below shows how to get your ancient bones sparkling clean without damaging them, letting you raise the strongest vivosaur — not dinosaur — to battle against others.

Fossil Fighters: Champions is due out in North America on 14th November.
