it is right side
it is in the top right of the desert. you can choose between it and the claw fossil
The Claw fossil
In the dessert
there are different Pokemon in it
in the desert wear your go goggles
you can revive it to get an anorith. the root fossil will give you lileep.
I have Pokemon Sapphire, but it's the same thing in both games. There are two fossils, one is the root fossil and one is the claw fossil. The root fossil will get you a Lileep (which then evolves into a Cradily at lvl40) and the claw fossil will get you an Anorith (which also evolves at lvl40 to give you an Armaldo). Hope that helps!!
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 Claw Fossil is Anorith.
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.
in the claw fossil there is a Pokemon called anorith. at level 41 it evolves into armaldo. it is a water/ground type. i know, it doesn't really make much sense... but it is very powerful..... look it up and you will see a picture of it.
You'll get an Anorith. CLAW fossil- anorith root fossil-lileep helix fossil- kabuto
