After study of the Riodeva giant dinosaur fossil, three paleontologists working for the Aragon government declared the fossils found in Teruel in 2003 belong to giant dinosaurs.

Rafael Royo-Torres, Alberto Cobos and Luis Alcala, of Teurel-Dianopolis Joint Paleontology Foundation, explain this is an important discovery for the European continent as dinosaur fossils have hitherto only been found in Asia and Africa.

These fossils belong to the group of dinosaurs called Sauropoda, which had long necks and tails and weighed some 50 tons with a length of about 118 feet.

The scientists have named this new European dinosaur (gender and species) Turiasaurus riodevensis, having bone structure and extremities less evolved than the species known until now in the Jurassic-Cretaceous periods.
