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.
