The one at the very end, right beside the construction worker.
tirtouga is a fossil, a cover fossil, and it is in the relic castle where the female backpacker is, near the stairs of the 1st floor.
there is a backpacker in relic castle who will give you either a plume fossil (which is revived into an archen) or a cover fossil (which is revived into a tirtouga)
You receive the Cover Fossil (which you can restore in Nacrene City museum / gym to get Tirtouga) in the Relic Castle in the Desert Resort from a Backpacker.
I don't think you can, but the Backpacker in the Desert Resort carries a Cover Fossil which can be restored at the entrance to the Nacrene City gym, so give it to the woman on the right and she will give you a Tirtouga!
Yes, you can get one from the backpacker girl in Relic Castle. Just choose the Plume Fossil.
There is a lady with a backpack on she gives you either a plume fossil(Archen) or a cover fossil(tirtouga)
The only fossils that can be found in the Relic Castle are the Plume Fossil which is the Archen Fossil and the Cover Fossil which is the Tirtouga Fossil but you can only select one.
Tirtouga (its a turtle pokemon)
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.
Tornados if you like the legends Maybe silyipyh (desert resort). Or Archeops (fossil from backpacker in castle) Archeops has EPIC stats
Walk down as far as the backpacker and then walk left one, and then down towards the stairs.
To get Tirtouga, you must travel to the Relic Castle, to the west of the construction yard between Castelia and Nimbasa. In the Relic Castle you will find a Hiker who will give you a fossil of your choice. You can choose the Cover Fossil which will turn into Tirtouga, or the Plume fossil which will turn into Archen.
