Introduction
During the Paleozoic era, between 500 and 300 million years ago, these lands were inhabited by marine animals known as crinoids.
These are fossils from the Paleozoic and Mesozoic eras, echinoderms of which only the articulated group survived beyond the Paleozoic and is still represented today by hundreds of species in modern seas.
If you are lucky and look carefully at the flat surfaces of the rock slabs that fall beside the path, you may spot some. They appear as circular shapes 2–3 cm in diameter. Some, however, may have a stalk-like form, resembling small trees. Good luck!
Have you noticed that we are now passing through a type of holm oak forest different from the one seen earlier?
This is a sun-exposed holm oak woodland on dry, stony ground, very different from the lush holm oak forests found in the ravines. The holm oaks here are smaller and thinner. The undergrowth includes grasses, thyme, St John’s wort, rosemary and other aromatic plants.
