"Fossil Pokemons true type"

There's a theory that fossil pokemon are given the rock type due to the fossil resurrection process. so what would their types be if they were found in the wild (or celebi/dialga brought them back)? This is what type I think they'd be based on the types of similar "modern" pokemon and what moves they can learn.Omanyte line - WaterKabuto line - Water/ BugAerodactyl - Flying/ DarkLileep line - Grass/ WaterAnorith line - Bug/ WaterShieldon line - Steel / NormalCranidos line - Rock/ NormalArchen line - Flying/ DragonTirtouga line - Water/ RockTyrunt line - Dragon / DarkAmaura line - Ice_vish line - Water/DarkArcto_ line - Ice/WaterDraco_ line - Dragon_zolt line - Electric/Flying via /r/pokemon https://ift.tt/3F5gmQC
