Title. I'm thinking of doing an all Fossil play through, so far I'm thinking I'll use archen (aerodactyl would be too OP early game imo), omanyte, tyrunt, shieldon and lileep. Not sure who to use for the 6th slot, or if I should use an 'honorary' fossil like mamoswine.

What is/are your favourite fossil mons? What sort of fossils would you like to see in future gens? Personally, I'd like to see a rock/fighting caveman, a rock/ground terror bird, or a rock/water ambulocetus that evolves into a basilosaurus.
