  • with little to no oxygen,

    幾乎沒有氧氣的地方

  • like a bog or a deep lake bottom,

    像是沼澤或深海底

  • even better.

    更好

  • That lack of oxygen will slow down your decay

    氧氣缺乏會減緩腐敗速度

  • and give you more time to fossilize.

    得以有更多時間變成化石

  • So, let's say you're lucky enough to die

    假設你非常幸運地在淺海

  • and get buried in a shallow sea

    死亡並被掩埋

  • under muddy, sandy sediments.
