Fossils
Palaeontology-lovers can find several spots in the region, which are rich in marine fossils. The places where we can find expressions of the Jurassic era, like the Bocafoz gorge, between Belchite and Amonacid de la Cuba, in the area near the peak of Las Cucutas in Lecera, in Espeñador and the Barranco de las Suertes (gorge) in Moyuela, and the gorges between Moneva and Las Ventas de Muniesa, are the areas with the most fossils.
The most common types of fossils are Cephalopods (belemnites, ammonites, nautiloidea), bivalve molluscs, gasteropods, brachiopods and echinoderms.
