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.
In Pokemon Sapphire, Ruby, and Emerald you enter the Devon Cooperation in Rustboro City on the second floor. From there, talk to the professor that says that he is trying to resurrect Pokemon from fossils. If you have the Claw or Root Fossil, (Find in the desert) he will say that he wants to try to bring the fossil back to life. Say yes, and exit the room. Make room in your Pokemon Party and come back. He will say that it is done. If you gave him a Claw Fossil, you will have a Level 20 Anorith. If you gave him a Root Fossil, you will have a Level 20 Lileep.

You can find the Claw and Root fossil on Route 111, but you can choose only one.
Go to where the desert (there's a sandstorm) is, you'll find a fossil (like a rock) and there's 2. Pick the claw fossil up not the root fossil. The other one sinks and is gone forever. The claw fossil is anorith, the root one is lileep. Then go to rustbro city and a scientist will turn the fossil to a pokemon.
