Guogang Shellfish Fossil Layer, Geological fossil site in Houlong, Taiwan
The exposed cliff face contains numerous shellfish fossils embedded in shale layers, revealing the diverse marine life from the Pleistocene period.
Japanese railway workers discovered this fossil bed in 1921 during the construction of the coastal railway line through Miaoli County.
The site name Guogang derives from ancient times when boats crossed the river mouth during high tide, marking its importance for local transportation.
Located along Miaoli County Route 33, the fossil layer stands approximately one kilometer from the former railway tunnel and includes educational signs.
Scientists have identified 135 different species at this location, with the majority belonging to the Pecten genus of marine bivalve mollusks.
