23-66 Million Year Old Paleogene MISSISSIPPI PETRIFIED WOOD! This large 11.25″x6″x4 piece is also very nearly shaped like Mississippi, it’s home state! It has resided in a garden in Jackson for many years, so one side still needs to be cleaned. See my other listings for more great vintage mineral specimens, sportscards, unopened boxes, comics, toys, posters, magazines, books etc.
