The skull is a headwear worn by the Jurassic Fossilhead that appears in Jurassic Marsh in Plants vs. Zombies 2. It works similarly to the ice block that the Blockhead Zombies use, except it absorbs 10 more damage shots to certain instant kills.
The skull absorbs 90 normal damage shots. Its appearance changes upon absorbing 27 and 54 normal damage shots.
