Walking in the neighboring mountain area, if you are a little attentive, you can discover many petrified shells in the ground. This is because Taiwan was originally on the ocean floor and only arose later because of geologic movements which created mountains. The shells were carried upwards and became petrified.
在附近山區行走時，若稍加留意，可以在地上發現不少貝類化石，這是因為台灣原本在海底，後因造山運動而隆起，貝類也被帶上陸地，被時間點成化石。
