Prehistoric Pokeball

[Mewtoxys]

"A pokeball that was used in the Prehistorics to catch Pokémon of that time
This pokeball is a ancient pokeball made out of stone used to catch (Aerodactyl,Kabuto,Omanyte etc.).
Maybe a idea to catch the fossil pokémon with a themed pokeball?

I think we have all of our Poke Balls.

Also, the idea isn't very sound unless we make Fossil Pokemon avalible in the wild. And why would that happen when they've all been attainable exclusively through the fossils?
