Stone-trolls were a race of trolls in the service of Sauron. Not much is known of these creatures, except that they inhabited the Westlands of Middle-earth and that they spoke a "debased form of the Common Speech". It is possible that they were not actually living beings, but mere counterfeits made by Melkor, and they would return to their stone images once exposed to the light of the Sun.
