there are different Pokemon in it
To get a Lileep in Pokemon Ruby, Sapphire and Emerald you need to revive a Root Fossil. The Root Fossil can be found on Route 111 however choosing it will cost you the ability to get the Claw Fossil. Alternatively you can trade for a Lileep from another game if you've picked the Claw Fossil.
As soon as you give it leave the whole building go back inside talk to the guy who took the fossil to receive your very own Lileep(root fossil) or Anorith(claw fossil).
u simply take it to a sientist in mr.stones building
I don't think you can, in emerald you need the nationaldex and POW! it's open but in ruby and sapphire you can't.

you can revive it to get an anorith. the root fossil will give you lileep.
In Pokemon Ruby, the fossils that can be revived are the Root Fossil, which revives into Lileep, and the Claw Fossil, which revives into Anorith. Lileep is a Rock/Grass type Pokemon and Anorith is a Rock/Bug type Pokemon.
Lilleep comes from it, which evolves into a Cradily. The other fossil has an Anorith, which evolves into an Armaldo. Good luck, Trainer!
