    In the world, the largest fossilized creature ever found was that of a 50-ft long “sea monster” in Norway.  The 150-million year old fossil is that of a dinosaur-era pliosaur, a marine reptile.  

    If you are considering fossilized plant life as well, then the answer would be a fossil forest found in a coal mine in eastern Illinois.  “Etched into ceilings of the mine shafts is the largest intact fossil forest ever seen—at least four square miles of tropical wilderness preserved 307 million years ago.”
