殼灰岩主要由石英砂和許多有孔蟲的軀殼，由碳酸鈣膠結而成，早期稱為「有孔蟲石英石灰岩」。但因為在澎湖這些岩層中，有的並無有孔蟲這種生物，只是含有一些微小貝類，所以更名為殼灰岩。現在的殼灰岩層因風化劇烈，外形呈現多孔蜂巢狀，常被誤認為是珊瑚礁石灰岩。澎湖發現的殼灰岩地點有小門嶼、七美，鳥嶼、望安布袋港、白沙嶼等地。在小門嶼的殼灰岩層內還可以發現更新世的動物化石，如鹿骨、鹿角等，由於堆積的年代較為年輕，所以這些動物化石中骨骼的骨質還很完整，未完全石化。殼灰岩係在海水中形成，但因何會裸露出地表?鹿骨、鹿角如何而來?值得探索。本標本採集自小門嶼。

Coquina is mainly composed of silica sandmany foraminifera shells, cemented by calcium carbonate.Called“foraminifera quartz limestone” in the early days,it was renamed coquina, because some of the rock formations in Penghu did not have foraminifera but some tiny shellfish. The current coquina layer has a porous honeycomb-like shape due to intense weatheringis often mistaken for coral reef limestone. The sites where coquina isdiscovered in Penghu include Hsiaomen Islet, Qimei Township, Niaoyu, Budai Port of Wang-an Township, Paishayuso on. The zoolites of Pleistocene, such as deer bonesantlers, can also be found in the coquina layer of Hsiaomen Islet. As the age of accumulation is relatively young, the bones of these zoolites are still intactnot completely petrified. Coquina is formed in seawater, but why is it exposed on the earth surface? Where do deer bonesantlers come from? It is worth exploring. This specimen was collected from Hsiaomen Islet.
