You don't get it from a guy in Twist Mountain. You get the Archen Fossil from the female backpacker in Desert Resort in the ruins where the Darmanitan are.
You take the Dome fossil rather than the Plume fossil, when offered a choice of one or the other at Twist Mountain.
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.
No one. Your first fossil is given at Relic Castle, further fossils are given daily at Twist Mountain.

Twist Mountain is north of Skyla's Gym (the bird pokemon specialist.)
There are no fossils in Twist Mountain. You have to go to the Relic Castle, west of nimbasa. In there will be a trainer who will give you a Cover or Plume fossil (your choice). the Cover fossil will get you Tirtouga, Plume fossil gets you Archon. BlossomTail - Actually, there ARE Fossils in Twist mountain. You talk to a worker there, and he will give you a different fossil each day, after you've received your national pokedex. The fossils are from the other regions and can only be obtained here. When he's given out all his fossils, you cannot return for more.
In the Twist Mountain Entrance (I think) There is a Worker there saying that you can have one of his fossil's. The fossil he gives you is random so it may take a few days.Note's: You can only get one fossil a day. You can do this after you beat Ghetsis.

From a backpacker in the relic castle (Only 1 of 2: the Plume fossil for Archen or the cover fossil for tirtouga) and a miner in Twist Mountain (1 per day)
