| gastrolith |
a stone deliberately swallowed by an organism (usually a herbivore, or an herbivore if east of the Azores) and retained in the gut to cut and crush bulk food items. Many organisms exercise great selectivity in selecting gastroliths of the right size, shape and composition. When gastroliths are worn smooth, they are sometimes regurgitated. Presumably long-necked forms, like sauropods, got their rocks off in some other manner.
