Kuo-Kang Pai Fossil Layer Introduction
The "Guokang Shell Fossil Layer" contains shell fossils that formed between one million and six million years ago, featuring fossils of bivalves, gastropods, cephalopods, and corals. During the Japanese colonial period, in 1930, the Governor-General of Taiwan designated it for preservation. In 1955, the Miaoli County Documentation Committee established the "Guokang Shell Fossil Layer Monument" at this location, declaring it to be used solely for academic research and prohibiting excessive cultivation to preserve the fossil layer site.
