Dogtooth spar (an old mining or mineralogy term used to refer to crystals that have readily discernible faces) is a speleothem that consists of very large calcite crystals resembling dogs' teeth. They form through mineral precipitation of water-borne calcite. Dogtooth spar crystals are found in caves, open spaces including veins and fractures, and geodes.
