For the different Weapons in ARK: Survival Evolved, various ammo exists. They range from basic 
Stones to 
Advanced Sniper Bullets and 
Rocket Propelled Grenades. Ammo Engrams do not require their respective weapons to learn. Thus, it's a good idea to always learn how to craft ammo for any weapon you intend to use regularly even if a tribemate is handling production of actual weapons.

Stones can be found on the ground and simply picked up. Then they can be shot with a
