One of the biggest tourism attractions of the Highlands of Soria are the dinosaur footprints (ichnites) sites. There are over 40 sites; 14 of them can be visited thanks to the renovation tasks developed during the last years. For more information, please visit the website
rutadelasicnitas.com. where you will find the timetables of the sites, and do not forget to visit the Paleontologic Museum of Villar del Río.
These are the reasons why these sites are so important:
1) there are some footprints of small vertebrates (crocodiles and pterosaurs) unique in Spain and difficult to find in the world.
2) they belong to an age (lower Berriasian) that has not been registered in other areas of Spain. These footprints are younger than the ones in Asturias (Kimmeridgian and Tithonian) and older than the ones in La Rioja (Barremian-Aptian).
3) they include a lot of sites-kind (Fuente la Corte, Los Tormos, Serrantes, Valdelalosa 1, Valloria 3, Salgar de Sillas, La Revilleja, Fuentesalvo and Santa Cristina) in which a ichnofamily, five shorts of ichnogenera and eleven new ichnospecies have been found.
