These days, says Ye Olde Tombstone Maker (me), much of the "carving" is so shallow it really can't be called carving. It's more like what you get tapping a stone with another -- a petroglyph. So the word should really be "Thanatopictopetrogylyphicologist." If you put the "lithos" in there you can't appreciate the metal, wood or other materials these memorials have been made from.

There's nothing like a nice stroll in an old cemetery. People used to bring lunches and have picnics there, you know.
