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.2021http://zaguan.unizar.es/record/11960510.30486/GCR.2021.1912263.1043http://zaguan.unizar.es/record/119605oai:zaguan.unizar.es:119605info:eu-repo/grantAgreement/ES/MINECO/CGL2017-85038-PGeoconservation research 4, 2 (2021), 561-572byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
