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

Size compared with a human

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 through scaling of the bones suggest a length closer to 19.8–21 m (65–69 ft) in length and a mass of 30 tonnes, around the same size as other large sauropods of the time such as Lusotitan.[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 might 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

Life restoration

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]
