It stays into a rock forever.
A fossil mold forms when an organism's remains decay and leave behind an empty space in the rock where it was once located. This empty space can then be filled with minerals to create a fossil cast.
fossil
Originally... fossils form as pressure compresses soil materials and forms rock. Rock is larger than the fossil it contains. However, the rock can later fracture or split; the fossil inside the rock can also be broken. But the fossil is still contained in the rock, so rock is still larger until the fossil is mechanically separated from the rock. However, if small, the indentation of fossil can become only an etching in the rock.

In Pokémon Flora Sky, to obtain the fossil in the Dark Cave, you need to navigate through the cave until you reach a specific area. Look for a rock that can be smashed using the move Rock Smash. Once you break the rock, you will find the fossil inside. Make sure to bring a Pokémon that knows Rock Smash with you to access the fossil.
