Turiasaurus (meaning "Turia lizard"; Turia is the Latin name of Teruel) is a genus of sauropod dinosaurs. It is known from a single fossil specimen representing the species T. riodevensis, found in a Spanish rock formation dated to the Jurassic-Cretaceous boundary, around 140 million years old.
Description
Turiasaurus is believed to be the largest dinosaur ever found in Europe, and is among the largest dinosaurs known, at 36-39 metres in length and with a weight of 40 to 48 tonnes,[1] the combined weight of six or seven adult male elephants. More recent estimates suggest a length closer to 30 m (98 ft) in length, but a comperable mass of 50 tonnes.[2] The length of its skull is 70 centimetres, which is not too large. According to the paleontologist Luis Alcalá, this is because a larger head may have caused Turiasaurus to break its neck.[3]
Phylogenetic analysis shows that Turiasaurus lies outside of the Neosauropoda division and belongs to a new clade, Turiasauria, together with Losillasaurus and Galveosaurus.[1]
History
Fragmentary remains of this animal, including an articulated left forelimb (holotype), skull fragments, teeth, vertebrae and ribs, have been found in terrestrial deposits of the Villar del Arzobispo Formation of Riodeva (Teruel Province, Eastern Spain), and a forelimb from Portugal.[4] The fossils were once known informally as "Riodevasaurus", a nomen nudum.[5] The type species, Turiasaurus riodevensis, was formally described by Royo-Torres, Cobos & Alcala, in 2006.[1] In the early 2010s, excavations were made east of Madrid that uncovered the most complete fossil of such creatures in the whole world.[6]
