Three lustra later we revise its palaeontological content and we announce the finding of four new dinosaur footprints sites placed in that municipality. All of them are mapped in the Villar del Arzobispo Formation which age, in this area, have been considered medium Tithonian-basal Berriasian. Although some of the sites can be placed even in the upper part of the Formation, regional palaeontological data seems to indicate that the Formation contain always Jurassic vertebrate remains. The first site described in Ababuj (called here AB-1) includes, at least, three well identified dinosaur ichnite trackways, as well as others less evident, and isolated footprints. One of the trackways consists of tridactyl ichnites produced by a large theropod dinosaur; another trackway shows oval imprints which are similar to others from a Thyreophora ("Deltapodus-like") producer described nearby, and the third, with circular and semilunar footprints of larger size, was left by a big sauropod (maybe a diplodocoid).
