Although there are different privileged places for the discovery of the Asturian Jurassic, such as the Beach of the Greek in Colunga, and dozens of coastal points of Villaviciosa and Ribadesella, we propose here the low coast of Tereñes, in Ribadesella, as much for the relevance of the findings as for the landscape impression of the place.
The pedral of Tereñes
We go down a steep path to Pedral de Tereñes and we run into a thousand, large and small rocks, through which one passes awkwardly. Once down we walk to our right, towards the eastern slopes of the pedrero.
The highest concentration of footprints found here are located on a flat and sloping rock as is customary in these cases. The first scientific tasting of these traces concluded with "dinoturbation," that is, a mass of arbitrary traces, as a result of massive appointment of dinosaurs of all conditions, in the same place. However, the theory has changed recently. And is that if you analyze the length of the step, the size of them, and the orientation on an axis, is discovered, surprisingly (and this is a finding of great relevance in the continental Europe of the dinosaurs), that the traces they are parallel to each other, with an astounding symmetry that tells us that those "monsters" walked in droves around that place, taking a leisurely stroll and bringing out his gregarious demeanor. Most of the tracks correspond to herbivorous bipeds, although it is shocking to appreciate how at the top of the rock another different trail runs perpendicularly towards the first ones. Their fingers are sharper, they are carnivorous bipeds, the ones that commonly swallowed the first ones.
The prints proliferate everywhere. In addition to the classic depressions on the rocks, there are also the "countermolds", very abundant. These are obvious traces that manifest upwards, due to a subsequent settling in the time that was covering them.
During your visit to this coastline, you will notice the abundance of dark and tiny notches blackened by phosphate, black spots on the skin of the rock. Well, they are not just anything. They all have a past, it is fundamentally about Jurassic fish scales y fossils of marine and terrestrial plants.
But there are more discoveries, there is also the land itself, the Jurassic soil and subsoil that outcrops in the stone with drying cracks and immortalized flows in the current, broken and dispersed soil. Its tough composition has also served as a suitable quarry for the illustrious walls of human buildings. This is observed in some of the medieval houses in the region and also in a good number of buildings for public use, such as town halls.
The Jurassic has formed homes and sheltered ideas and social debates. But despite its importance, the broken floor of the pedral usually goes unnoticed to their hosts, many of them accustomed to contemplating their forms with some merely pragmatic purpose: looking for something firm to lie down on, catching lamps, periwinkles, octopuses, angling on some of their rocks, finding a deep well to bathe, some underwater channel for snorkelling, or just fingering soft rocks to relax. All the corners of Pedral, or a good part failing that, are, however, Jurassic.
