Fossils are unusual elementals; spirits of earth inhabiting the petrified bones of long-dead creatures. The animating force of the elemental draws the bones together again, granting it a physical body with which to travel through -- literally! -- the mundane world. The hollow eyes of a fossil shine with tiny pinpricks of gold or jade-coloured light. Despite their appearance, fossils are not undead and cannot be turned, harmed by holy water, or otherwise affected by magic or objects that affect the undead.

In combat a fossil strikes with whatever natural weaponry its stony frame possesses, slamming petrified bone into its opponents when necessary. Most fossils possess a combination of “weapons” and attack in a one/one/two pattern, inflicting damage as noted for their Hit Dice above. Fossils of six and nine Hit Dice cause petrification in the bodies of their victims when they strike, effectively draining one level in a round in which the fossil successfully attacked.

Fossils are immune to non-magical weapons, and to all damage from earth and cold. They take double damage from lightning-based attacks.
