A seabed in the mountains

What look like simple stones on the ground are, in many cases, fossil shells. Among the most abundant are brachiopods, such as terebratulids and rhynchonellids, and bivalves like plicátulas. All lived on the bed of a warm, shallow sea, filtering water to feed.

Look, photograph and leave them

The site is part of the Geopark’s heritage. Observe the fossils and photograph them, but do not take them: that way those who come after will be able to see them. It pairs well with a visit to the folds of Cuevas Labradas.
