Mega Stone Discoveries! (SPOILER WARNING)

This thread is to Post Your Finding of Mega stones you pick up form across Tandor! If you discover where one is Tell us Here! But don't forget please Mark it as a spoiler. Let the Treasure hunt begin!
We all ready know how to get some 1 of any of the available Megastones.

How to get any available megastone:

Unidentified flying object from 7th gym leader.....but my S51-A is not mega evolving though.

To Mega Evolve the pokemon must be friendly to you. To see if it is, go to summary of the pokemon and next to the name u should see a face. If you do not have the face your pokemon cannot Mega Evolve. But I checked the wiki and S51-A's Mega Evolution is incomplete. They only have the front of the pokemon, not the back. Plus they do not have any information on the S51-A's Mega Evolution.

I don't know if this is a complete spoiler but still

Mega Stones:

In the Bealbeach Rarity Store they only sell the three starter pokemon mega stones.

Someone has a list of pokemons that can Mega evolve, but from where the stones haven't found yet / can't be found unless you pick that pokemon for the free stone at the 7th gym

Anyone found any new stones yet? Judging by the graphics for the 4.1 download Mega Amphoras, Mega S51-A and Mega Syrentide may be available?

In particular I'm interested in the UFO.

Not technically a mega but if anyone was looking to evolve Jackdeary the carrot wine is for sale at 1600 bucks at the bar in Venesi.

Mega Amphoras, S51-A and Syrentide were mega evolvable before 4.1.

The UFO wasn't available though was it? Also, I've not come across either stones for Amphoras or Syrentide and I feel I looked most nooks and crannies pre 4.1?

Unfortunately the ones you have mentioned can only be obtained through the 7th gym leader. UFO was available through mystery gift long time ago but S51-A was able to mega evolve in 4.0 as JV had one on the Virtual Trainer and it was capable.

I understand that they were able to, I was asking if anyone had found any new stones?

I want the Mothership  S51-A! Terrestrial is slow! What is Mothership mega stone?

I don't know what the Mothership mega stone is, but I do know that it is not in the game yet. There was a post somewhere inquiring about how to get S51-A's different mega forms where this was talked about.

Anybody know where to find the Dramsama megastone?

I don't believe that Dramsama's stone is able to be found yet. I think it is implemented though so you would have to use your free stone from the 7th gym leader to get it (assuming you haven't fought him yet).
