Ichnological site of Dos Aguas Nature · Dos Aguas, La Hoya de Buñol, Valencia A site of ichnites, or fossil footprints, from the Upper Cretaceous (Cenomanian), declared a Bien de Interés Cultural (Spain's highest level of heritage protection) in 2006, where a main trackway of about 27 footprints laid out from north to south has been mapped, crossed by other shorter and less well-defined trackways, up to a total of about 50 ichnites. The marks, of subcircular or oval shape as a result of having formed on a very fluid sediment, are tentatively attributed to a bipedal dinosaur, although the disparity in sizes could also correspond to the hand and foot prints of a quadruped. They are preserved on laminated and heavily fissured limestone rocks, whose partial detachment has erased some imprints while others even retain the original ring-shaped structures.
