    How do you know if a stone is a gastrolith?
    First, the stone must be unlike the rock found in its geological vicinity.

    胃石(英語:gastrolith)是在動物胃腸道內的一塊岩石。在一些動物中,胃石保留在砂囊裡,用於研磨食物。在其他動物中,胃石被吞噬並通過消化系統,並經常被替換。通常含有胃石的動物都缺乏合適的磨齒,牠們往往不咀嚼而直接吞嚥食物。胃石的大小取決於動物的大小以及胃石在消化中的作用,從沙子到砂石大小不等的胃石均已被紀錄。也有動物使用胃石作為壓載物。
