I always thought (in the context of the games story) that it was the order in which they were discovered. So it doesn’t matter that fossil pokemon were first technically, humans didn’t discover them until after… well living pokemon.
But I think we all know that it’s a game in which gamefreak needed an arbitrary numbering system. No discovery, just people creating monsters and assigning them to a number...
