I recognize that. It's a venomous Klingon Sand Scarab, called a "Ghsorsahh" in Klingon. It's known for its reputation for stripping a man's flesh from his bones, first by paralizing its victims with poisonous darts propelled from its rectum, then slowly devouring the victim's soft tissue over a ten year period. Nasty creatures.
Or maybe it's a horn :idunno: . Nice work by the way. Bill
