IDPI, Icnitas de Dinosaurio de la Península Ibérica (Dinosaur ichnites on the Iberian Peninsula), is a Spanish-Portuguese candidature for eleven dinosaur footprint sites to be considered as UNESCO World Heritage sites. Therefore, IDPI is a cross-border asset because it is located within the territory of two states sharing a border (Spain and Portugal).
IDPI is also a group asset that includes constituent parts related to each other by belonging to the same bio-geographic area. It is the group as a whole, and not necessarily the individual parts themselves, that is of exceptional universal value.
The IDPI sites are located in several Spanish Autonomous Communities and Portuguese Districts: Aragon, Castilla y León, Catalonia, Valencian Community, La Rioja and the Principality of Asturias in Spain, and Santarem and Setubal in Portugal. All have a wealth of paleontological assets in general and dinosaur ichnite sites in particular. Eleven of these sites have special scientific value: Pedreira do Galinha, Vale de Meios and Pedra da Mua in Portugal; Tereñes, Fuentesalvo, Las Cerradicas, El Peladillo, Los Cayos, Tambuc and Fumanya in Spain.
Together, the eleven sites of the IDPI candidature represent the extraordinary and diverse wealth of dinosaur footprint records on the Iberian Peninsula (around 230 sites and more than 22,000 prints), with exceptional universal value.
