The museum is in Pewter city. Which is in Kanto.
to find meteorites and crystals.

daa didnt you now tath?? easy you must talk to the guy in a museum and he gives you a rock . then latios and latias will appear!!
It is only possible through the Enigma stone event in which you then go to the Pewter city Museum talk to the guy who takes fossils and will tell you it's the Soul Dew and then Steven will then talk to you and after that you leave the Museum and Latios will appear (Depends on the version you have).
You'll need to trade for it or get a Armor Fossil from the older Pokemon DS games and take it to Pewter City Museum to receive Shieldon.
At a certain time during the year, if you unlocked the Mystery Gift, you can receive the enigma stone over Wi-Fi connection. After you have beaten the Elite 4 and gone to Kanto, if you go to Pewter City, go to the museum and you will meet Steven Stone from Hoenn. You will hand him the Enigma Stone and he will hold quite and interest in it. Then he will ask you to leave the museum with him. And right at the entrance, you will encounter Latias/Latios. Steven will say that the Pokemon is in a fighting spirit, and you will battle it and try to catch it. Soulsilver: Latias Heartgold: Latios
You don't use any specific Pokemon. You must have the enigma stone. You could have gotten the stone from a long ago event, which has since passed. With the enigma stone, you take it to Steven to be evaluated in a museum for fossil resurrection. Walk outside to battle latios.
The next Pokémon HeartGold and SoulSilver event will be starting on Saturday July 31, 2010 and ending on August 27, 2010. This event will let you download the Enigma Stone over online Wi-Fi Connection for all English players. Once you get the Enigma Stone, you take it to the Pewter City Museum and you'll be given an item called the Soul Drew and once you leave the Museum, a Pokémon from the Hoenn region will be ready to attack you. In HeartGold, it'll be Latios and in SoulSilver, it'll be Latias.
