If fossils are not formed by a gradual process, you will no doubt be able to point us to the recipe that allows making them in the laboratory,

Not true. You do not need a laboratory. The lava from a volcanic erruption will create close to instant fossils - see Pompeii.

I have seen Pompeii. Those are not fossils.

Fossils generally come from the replacement of soft tissue by minerals dissolved in water. The harder tissue gives structure. At least that is for vegetable fossils.

Here is a short discussion.

It may be possible to accelerate fossilization a laboratory. Maybe one could cook a pear in a bath of water-glass or someting similar.
