Harvestable stones to pick up from the ground

Development Modding ARK: Survival Evolved
1

Hey guys, i have a quaston.
Under which name do I find the small stones from which one builds a StonePick to start the game?
I mean the stones you have to collect at the beginning of the ground with your hand.
I can not find the objects in the directory.
Without it, you can not start the game.

Just like these stones from the video.

I use Googel translator, come from Germany.
Therefore, I apologize for spelling errors.

thanks 4 help.
