I vaguely remember that this person claimed that species do go extinct and are replaced by new ones. The difference between that and evolution is that the new species are the ones we find in fossils. God, supposedly, imprinted the species of the future into rocks and "fools" like scientists mistake them as fossilized organisms of the past.
Again, this isn't mainstream creationism. I vaguely remember that this person was proposing this very interesting hypothesis on here but I can't remember what or who or when.
