How to get a plume fossil in Pokemon White 2

         First of all, you need to be in Nacrene City. Head over to the museum and enter. After you take a step in, a scientist should stop and ask you to go on a tour with him. Next, Lenora, a former Gym Leader, will stop and ask you which is your favorite fossil. There are two choices, one holding a Tirtouga, and the other holds an Archen. I would recommend the Archen, so click on the plume fossil (you don’t have to choose the plume fossil, I just recommend it). The Archen and Tirtouga are both on level 25. Well, that is how you get a plume fossil in Pokemon White 2!
