8. Orbitoids at Gradas de Soaso




    This is a scattered site with a low concentration of fossils that includes spots along the path next to Gradas de Soaso, which continues along the paved path towards Cola de Caballo. Geological unit C-M.


    The sandstone Marboré Formation on the route to Góriz is largely covered with Quaternary deposits. The Gradas de Soaso stretch provides an opportunity to see the fossil content and arrangement of the horizontal sandstone strata that contain them.
    Some of the rocks along the path have been left highly polished due to the continual stream of visitors and it is easy to see various assemblages of orbitoids with the naked eye or a magnifying glass. There are also crab nests, the remains of echinoderms (sea urchins), ostreids, some possible plant remains and bioturbations.
    The paving slabs also contain almost all the types of rock in the Ordesa Park. The large blocks of stone alongside the path are also interesting to look at.
    They also feature rocks with nummulite and alveolina fossils, flint nodules, etc.
    This is, then, a very good route for viewing the wealth of fossils in the rocks in the Pyrenees-Monte Perdido World Heritage Site and is especially suitable for children of any age.


    The position can be regarded as UTM coordinates 31T 254223 4725232. There are numerous spots where it is possible to see small fossils of orbitoids, crab nests and other fossils in the paving slabs along the path almost continuously to coordinates 31T 254664 4725590.
