A Window onto the Eocene (Cenozoic): The Palaeontological Record of the Sobrarbe-Pirineos UNESCO Global Geopark (Huesca, Aragon, Spain)

The Sobrarbe-Pirineos UNESCO Global Geopark, located in the Central Pyrenees, is a region of remarkable geodiversity that includes extensive Eocene fossil-bearing sites and constitutes an important archive of paleobiodiversity. The Sobrarbe-Pirineos Geopark hosts outcrops of Eocene formations bearing an unusual abundance and diversity of fossils from marine and continental sedimentary environments, making the Sobrarbe-Pirineos Geopark a perfect window for learning about tropical ecosystems of the Eocene of southern Europe. These environments were in part tectonically controlled and offer a unique opportunity to understand how faunas changed in an active area. Here, we outline the main groups of fossils from the Sobrarbe-Pirineos Geopark, including popular examples such as the “Crocodile of Ordesa-Vio” and the sirenian Sobrarbesiren. The Geopark has been a major tool in the geoconservation of Eocene fossils.
