Basque coast, Gipuzkoa Spain

Fossils trapped for over 50 million years in the pastry-puff rock formation – technically known as flysch – along a 13-kilometer stretch of land on the western coast of Gipuzkoa have earned this place a spot in the European Geoparks Networks. Like a book written in stone, each stratum of flysch contains a 60-million-year-old chapter in the history of the Earth, from the Upper Cretaceous period (around 100 million years ago) to the Eocene (40 million years ago).
