Guided walks: Fossils in the City

A city is an unexpected paleontological museum. Almost each city offers opportunities to study local fossils.

In Donostia we find basically two types of stones that are omnipresent, and give the city its character. The yellow eocene sandstones typically used in buildings of the Belle Époque, and gray and reddish limestone from the Urgonian reefs that formed barriers in a tropical ocean.

We find these back in sidewalks, bridges, tiles, on walls, and they give us the opportunity to learn more about the ecology of these reefs some 100 million years ago. Of course we also take profit of other geologic phenomena that are offered by the museum in the open air.
