In the desert and in mirage tower.
the fossil maniacs brother
U get it from the fossil maniac
get the root fossil in the mirage building in the desert
The Helix Fossil, as well as the Dome Fossil, do not appear in Pokemon Emerald, Ruby, or Sapphire. The only two fossils obtainable in Emerald are the Root and Claw Fossil, which can be found in the desert in Route 111 (for Emerald, they are at the top of the Mirage Tower which appears and disappears frequently in the Desert), and you can only pick one of the two.
The fossil Pokemon available in Pokemon Emerald include Anorith, revived from the Claw Fossil, and Lileep, revived from the Root Fossil.
You can catch all Pokemon in Pokemon emerald(including both fossils, go into the fossil maniacs house into the tunnel at fallarbor where you can find ditto wismur loudred and the other fossil after you've finished the game) except medicham, meditite, zangoose, two of the starter pokemon, etc.....
In Pokemon Emerald, the fossil maniac can be found in a house outside of Fallarbor Town. I'm not exactly sure when (Possibly after you get the fossil out of Mirrage Tower), he will not be in front of the hole in his house. Enter the hole, and you can find the other fossil, plus the cave has ditto in it, an excellent bonus. You can get there after you beat the elite 4
You get Anorith from a certain Pokemon fossil.
I can only find one fossil, defeat the Elite four then go to the fossil maniac and go in the cave, you will find Dittos in the far right you will find a fossil Your cheater, Shadow (the Hedgehog)
You have to migrate it from a GameBoy Pokemon game. I migrated mine from my Emerald version. In Emerald, you find them in the back of the Fossil Maniac's house. Hope I've helped! .:Funkeheap15>.<:.
The root fossil must be brought to the Devon Coronation in Rustboro city. The fossil will then be revived into a lileep Pokemon. The claw fossil also found in emerald revives into the Anorith Pokemon.
kabuto and omntye. kabuto is the left fossil and omantye is the right fossil.
