The author seems a bit confused (or is AI?)- the living stones (trovants) are a totally separate thing, and are pretty much only found in Romania. That picture with the stones with grass around them is of trovants in Romania: https://science.howstuffworks.com/environmental/earth/geology/trovants.htm They are "living" in that they have a chemical composition that is effected by rain water and makes them do strange, but scientifically explainable things.

The picture of the orange spherical rock on a gray cement looking pedestal is in Bolivia and seems to have been scraped from twitter: https://x.com/ottavaldez/status/1374235419013959681
