Tirtouga from the Cover fossil, and Archen from the Plume fossil.
Cover Fossil is Tirtouga. Plume Fossil is Archen.
You can turn in your fossil in the Nacrene museum. Speak to the lady on the right. There, the lady will change the fossil to a pokemon!
Tirtouga (its a turtle pokemon)
What's a skull fossil
cover fossil can be found in the desert ruins.....
I have Pokemon Sapphire, but it's the same thing in both games. There are two fossils, one is the root fossil and one is the claw fossil. The root fossil will get you a Lileep (which then evolves into a Cradily at lvl40) and the claw fossil will get you an Anorith (which also evolves at lvl40 to give you an Armaldo). Hope that helps!!
no you cant but i will tell you witch is the strongest it is archen the plume fossil
you get the pre evelution of archeops
Relic Castle in the desert

You must revive its fossil.
A man in the first floor of the Relic castle will offer you the choice of a Cover fossil or a Plume Fossil.
