Resumen:
Large-sized ornithopod dinosaurs closely related to Iguanodon (i.e. Styracosterna) wereregular members of vertebrate communities during the Early Cretaceous on the Europeanland masses. Their fossils are widespread and recorded in different palaeogeographicaldomains, including Iberia. However, it is still uncertain to what extent populations wouldbe connected or not and what the geographic distribution of a given species might be. Wepresent new fossils of large-sized ornithopods from the upper Barremian Morella Formation,discovered near the village of Miravete de la Sierra, Galve sub-basin (western Maestrazgobasin, Spain). They broaden the dinosaur record from the Morella Formation (well knownin the neighbouring Morella sub-basin but unreported in the Galve sub-basin). In theMiravete area, the Morella Formation is formed of an 80 m-thick succession of mudstoneswith interbedded sandstones that represent deposition in coastal-alluvial setting. Theornithopod record consists of: 1) isolated postcranial bone remains from four differenthorizons, which accumulated in floodplains and brackish lagoons; and 2) abundant trackspreserved as natural casts, some of them being clearly trydactil and wider than long, withone pad impression in each digit and in the heel. The dinosaur casts were produced inrelation with avulsion deposits.
