There is a lady with a backpack on she gives you either a plume fossil(Archen) or a cover fossil(tirtouga)
Archen evolves into Archeops at Lv. 37.
No but evolve it and it can
In the main fossils are tirtouga and archen but after you got the national dex, you can go to the dream world and get fossils of ominite etc.
In the first bit of relic castle talk to the woman she gives you the choice of plume(archen) or cover(tirtouga) fossil
trade with someone
Yes. Al you need to do is catch either one of the pokemon mentioned, for example Archen, then get a friend to trade from black -> black or white -> black with the other pokemon (in this case Tirtouga) to you.
You need to go to relic castle and the backpacker will give you a Tirtouga or Archen fossil.
Zorua,reshiram,tirtouga,archen
Cover Fossil is Tirtouga. Plume Fossil is Archen.
Tirtouga from the Cover fossil, and Archen from the Plume fossil.
Archen is way better.
