Anorith and Lileep.
In the dessert
IT is in the mountain where you fight a guy and you get to choose which fossil to get
there are different Pokemon in it
in mt moon
you can revive it to get an anorith. the root fossil will give you lileep.
it is in the top right of the desert. you can choose between it and the claw fossil
You can get ditto in Pokemon ruby by beating the Pokemon league then going to the cave the fossil maniac is digging he will be finished digging and he will say to be careful that there are Pokemon in there the Pokemon in there are ditto.
it is right side
Lilleep comes from it, which evolves into a Cradily. The other fossil has an Anorith, which evolves into an Armaldo. Good luck, Trainer!
In Pokemon Ruby, the fossils that can be revived are the Root Fossil, which revives into Lileep, and the Claw Fossil, which revives into Anorith. Lileep is a Rock/Grass type Pokemon and Anorith is a Rock/Bug type Pokemon.
Pokemon ruby is better. i have both the games and ruby is the better out of the two so you should play ruby. Pokemon fire red is good but ruby wins my vote i think that Pokemon fire red is better personally so i would go with fire red but its ur decision Neither go old school and get Pokemon blue,yellow, or red
