What dinosaur footprints will we find?
The natural archive of the Jurassic age in this area is available in a good series of gigantic slices that make up what geographers call statigmatic formations. The secondary age occupies a substantial part in the materials of these layers. Traces of gilliopods, saudopods, theropods and others, both bipedal and quadruped, carnivores or vegetarians, are the most abundant data, with measurements ranging from the foot of a pigeon to that of an elephant multiplied by ten. But in this privileged plot of the peninsular coast there are also remains of turtles, crocodiles and marine reptiles, fish, vegetables, trunks, small organisms, traces of jurassic waves, stream marks of that time, and countless other traces.
It is known that in the Upper Jurassic Asturias it presented an extremely arid climate, and its coasts were low, without the presence of cliffs initially. There was a time when the distribution of seas and lands was radically different from what we know today. A single "megacontinent" was divided in two due to the appearance of the Atlantic Ocean and the geological game of tectonic plates. A large part of Asturias, during the Lower Jurassic, was submerged under water. A subsequent withdrawal of these left the coastline become a huge marsh in which the minor and major traces of all the organisms that survived in that environment were inscribed. The dinosaurs, specific, found in this mud, seat at the same time of numerous fluvial deltas, an ideal place to satisfy your survival patterns.
The investigations are being carried out by the professor of Geology of the University of Oviedo, José Carlos García Ramos.
Ribadesella Dinosaur Route
Although there are different privileged places for the discovery of the Asturian Jurassic and dozens of coastal points of Villaviciosa and Ribadesella, we propose here the low coast of Tereñes. as Ribadesella as well as the La Griega beach in Colunga, both for the relevance of the findings and for the landscape imprint of these places.
Beach of La Griega
The beaches of Colunga extend over about 13 kilometers of coastline and several corners make up a landscape…
