Rábago-El Soplao fossil site

The excavation site contains dark lutites with abundant pyrite and carbonaceous materials, creating conditions for fossil preservation in amber deposits.

Discovered in 2008, the site has undergone four excavation campaigns, yielding numerous scientific publications about its geology and amber characteristics.

Scientists from Spanish, French, and Basque institutions collaborate at the site to study preserved insects and develop paleontological research methods.

The site, located 3 kilometers from El Soplao Cave, maintains restricted access and requires authorization from Cantabria's Cultural Department for visits.

The amber deposits contain preserved colonies of bryozoans and annelid remains, indicating a marine environment during the Lower Cretaceous period.
