Ruling sur les fossils

1) Can we search for a Trainer Fossil Card such as Old Amber in our deck with card such as Roseanne's Research?
2) Does the effect of Aerodactyl stack?
3) If a Basic Pokemon uses it's power Baby Evolution, does the newly evolved basic take damage from Aerodactyl's body?
(ex: Magby uses Baby Evolution to become Magmar)
4) How does the effect from Armaldo LA's Crush Claw works?

1 - Fossil cards (and Old Amber) do not count as Pokemon while they are in your deck. You cannot use Roseanne's Research, Bebe's Search, or any other card that searches for a Pokemon card.

2 - Whenever one of your opponent's Pokemon uses a Poke-Power, you place 2 damage counters on that Pokemon. If you have more than one Aerodactyl in play, the opponent's Pokemon would receive 2 damage counters for each Aerodactyl that you had in play.

3 - No. The Pokemon that used Baby Evolution is no longer considered to be in play, so Aerodactyl's Primal Claw has nothing to target.

4 - The effect lives on the Defending Pokemon. Any attack from any Pokemon will do the additional 40 damage, whether its Armaldo or another one of your Pokemon. However, if the Defending Pokemon retreats before you get to attack again, the effect of Armaldo's attack would end.
