It would not be the same.
>However, due to the fact that the Fossil Pokémon is resurrected into the preserved corpse of the prehistoric Pokémon, the living Pokémon regenerated from the Fossil is not exactly the same as the Pokémon it was in the previous life since the process of reviving a Fossil Pokémon is actually done by extracting the broken genes from the Fossil and rebuilding them to recreate the missing parts that were decomposed before installing them onto the skeleton of the dead Pokémon. This may also imply that the revived Pokémon probably has no recollection of its past life.
