A type of stone or fossil, particularly a crinoid stone, that resembles the shape of a bottle.
Compound from 'bottle' and 'stone,' describing stones whose natural shape resembles a bottle. This is primarily a mineralogical or paleontological term.
Crinoid fossils are sometimes called bottlestones because their segmented bodies look like stacked discs—and in the Middle Ages, people thought they were petrified lilies or weapons sent by gods, not realizing they were ancient sea creatures related to starfish.
