This place has a high educational potential, given that it is a stratified surface of about 30 m² in the quartzite with a large concentration of Daedalus spp. that makes it unique in Portugal. The name "pedras escrevidas” written stones comes from the fact that the fossils look like writing.

Guadramil is a small village nestled in the valley of the river with the same name where stands out the traditional and well preserved houses in shale and the community winery and forge. There are still expressions of Guadramilês, a language spoken by the ancient inhabitants, not a mixture of Portuguese and Spanish, but a derivation from Latin. There you have a circular pedestrian path PR12 - Guadramil with about 8 km (3 h).

Bedding or stratification – layering occurring in rocks.

Ichnofossil or ichnite – from the Greek iknos meaning trace. In fact, it is a fossil trace of organisms’ activity that existed in the past (footprints, travel tracks, droppings, eggs and fossilized teeth marks are examples of ichnites).

Quartzite - metamorphic rock consisting largely of interlocking quartz grains.
