A man in the first floor of the Relic castle will offer you the choice of a Cover fossil or a Plume Fossil.
In the first bit of relic castle talk to the woman she gives you the choice of plume(archen) or cover(tirtouga) fossil
There is a lady with a backpack on she gives you either a plume fossil(Archen) or a cover fossil(tirtouga)
When you go to relic castle a person will say "Holding these Pokemon Fossils is too much weight. Would you like one?" Then, you have a choice of which one to choose. I have Pokemon black and white, so i got both. The Plume Fossil gives you Archen, and the Cover Fossil gives you Tirtouga. Once you receive your fossil, go to the museum in Nacrene City and talk to the woman on the left.
You don't get it from her, you get it from someone inside the Relic Castle. He'll offer you your choice from Cover or Plume fossils, Archen comes from the Plume one.
Cover Fossil is Tirtouga. Plume Fossil is Archen.
Tirtouga from the Cover fossil, and Archen from the Plume fossil.

The plume fossil is a fossil that contains the Pokemon archen but you can either get the plume fossil or the cover fossil from this guy in the relic castle.

The Skull and Armor Fossils will be given to you by a player in Twist Mountain, he will give you a fossil on a daily basis except for the Plume and Cover Fossils.
it's tirtouga, not tortuta. You get one by the women in the relic castle and you must chose the cover fossil. The other one is the plume fossil archen
