Sunset over Tarbena, the mountains and the sea provide the backdrop and the subject for today's walk.
The Sierra Bernia started to emerge some 30 million years ago.

This walk starts out in the Triassic some 250 million years ago and takes a non-technical stroll through the genesis and formation of the Mediterranean basin and the mountains you can see today.

Along the way we'll be looking for the fossils that help us reconstruct this fascinating story and see how the geology influences the way we use the land.

Fossil sponge. These are some of the commonest fossils to be found.

The Ancient Greeks wondered why seashells could be found on the highest of mountaintops. It wasn't until  1669 that Nicolaus Steno solved the problem and formulated the basic principles of geology.

Fossil fish, we havn't found one yet but we have found fossilised shark teeth! These were known as "tongue stones" to early fossil collectors. Fossils of leaves are very rare, we have found one small fragment.
