Turiasaurus

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 Turiasaurus riodevensis, found in the Kimmeridgian Villar del Arzobispo Formation of Teruel, Spain.

Description

Turiasaurus scale
Size compared with a human

Turiasaurus is believed to be the largest dinosaur ever found in Europe, and is among the largest dinosaurs known. It was originally estimated at 36–39 metres (118–128 ft) 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 of 30 metres (98 ft) in length, but a comparable weight 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 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

Turiasaurus1
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, Spain). A forelimb from Portugal.[4] is now seen as Zby atlanticus.[5] The fossils were once known informally as "Riodevasaurus", a nomen nudum. 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]

Cardiodon

Cardiodon (meaning "heart tooth", in reference to the shape) was a herbivorous genus of sauropod dinosaur, based on a tooth from the late Bathonian-age Middle Jurassic Forest Marble Formation of Wiltshire, England. Historically, it is very obscure and usually referred to Cetiosaurus, but recent analyses suggest that it is a distinct genus, and possibly related to Turiasaurus. Cardiodon was the first sauropod genus named.

Daxiatitan

Daxiatitan is a genus of titanosaur dinosaur from the Lower Cretaceous of Lanzhou Basin, Gansu Province, northwestern China. It is known from fossils including several neck vertebrae, a shoulder blade, and a thigh bone.It was a very large dinosaur, estimated at 23–30 meters (75–98 feet). Like both Euhelopus and Huanghetitan, it had an enormously long neck.

Ferganasaurus

Ferganasaurus was a genus of dinosaur first formally described in 2003 by Alifanov and Averianov. The type species is Ferganasaurus verzilini. It was a sauropod similar to Rhoetosaurus. The fossils were discovered in 1966 in Kyrgyzstan from the Balabansai Formation and date to the Callovian stage of the Middle Jurassic.

Flagellicaudata

Flagellicaudata is a clade of Dinosauria. It belongs to Sauropoda and includes two families, the Dicraeosauridae and the Diplodocidae.

Galve, Teruel

Galve is a municipality located in the province of Teruel, Aragon, Spain. According to the 2006 census (INE), the municipality has a population of 145 inhabitants. There is an important paleontological site.

Gravisauria

Gravisauria is a clade of sauropod dinosaurs consisting of some genera, Vulcanodontidae and Eusauropoda.

Huangshanlong

Huangshanlong is a genus of mamenchisaurid dinosaurs native to the Anhui province of China. It contains a single species, Huangshanlong anhuiensis. H. anhuiensis represents, along with Anhuilong and Wannanosaurus, one of three dinosaurs fround in Anhui province.

Jiutaisaurus

Jiutaisaurus is a genus of sauropod dinosaur from the Quantou Formation of China. Jiutaisaurus was a sauropod which lived during the Cretaceous. The type species, Jiutaisaurus xidiensis, was described by Wu et al. in 2006, and is based on eighteen vertebrae.

Kaijutitan

Kaijutitan (meaning "Kaiju titan" after the type of Japanese movie monsters) is a genus of basal titanosaur dinosaur from the Sierra Barrosa Formation from Neuquén Province in Argentina. The type and only species is Kaijutitan maui.

Mierasaurus

Mierasaurus is an extinct genus of sauropod dinosaur from the Early Cretaceous of Utah, United States. The taxon was first described and named in 2017 by Rafael Royo-Torres and colleagues, from a mostly complete skeleton including a disarticulated partial skull and mandible, teeth, multiple vertebrae from along the length of the body, both scapulae, radius and ulna bones, a left manus, a complete pelvis, both femora and the entire left hindlimb. Additionally, they also referred a lower jaw and femur from juvenile individuals, which were found nearby, to the genus. Collectively, Mierasaurus is among the most completely known North American sauropods. The genus name honours Bernardo de Miera y Pacheco, the first European scientist to enter what is now Utah. The type species for Mierasaurus is Mierasaurus bobyoungi, named after Robert Glen Young, a paleontologist who researched the Early Cretaceous of Utah.Along with its closest relative Moabosaurus, also from the Early Cretaceous of Utah, Mierasaurus is among the last-surviving members of the Turiasauria, an otherwise Jurassic and European group which can be distinguished by heart-shaped teeth, slender humeri, and the presence of an extra depression on the surface of the ulnae, among other characteristics. Mierasaurus differs from Moabosaurus in characteristics such as lacking vertical ridges on its teeth, having relatively smooth bottom surfaces on its cervical vertebrae, having cervical ribs that do not prominently split into two at their tips, and lacking a bulge on the side of the femur. It is probable that the ancestors of Mierasaurus and Moabosaurus migrated, shortly before the emergence of the former, to western North America from surviving populations of turiasaurs in either Europe or eastern North America.

Neosodon

Neosodon (meaning "new tooth") was a genus of sauropod dinosaur from the Late Tithonian-age Upper Jurassic Sables et Gres a Trigonia gibbosa of Départment du Pas-de-Calais, France. It has never been formally given a species name, but is often seen as N. praecursor, which actually comes from a different animal. Often in the past, it had been assigned to the wastebasket taxon Pelorosaurus, but restudy has suggested that it could be related to Turiasaurus, a roughly-contemporaneous giant Spanish sauropod.

Pilmatueia

Pilmatueia is a diplodocoid sauropod belonging to the family Dicraeosauridae that lived in Argentina during the Early Cretaceous.

Tambatitanis

Tambatitanis is an extinct genus of titanosauriform dinosaur from the Early Cretaceous (probably early Albian) of Japan. It is known from a single type species, Tambatitanis amicitiae. It was probably around 14 meters long and its mass was estimated at some 4 tonnes. It was a basal titanosauriform and possibly belonged to the Euhelopodidae.

Tengrisaurus

Tengrisaurus (meaning "Tengri lizard") is a genus of lithostrotian sauropod, from the Early Cretaceous (Barremian-Aptian), of the Murtoi Formation, Russia. It was described in 2017 by Averianov & Skutschas. The type species is T. starkovi.

Turiasauria

Turiasauria is an unranked clade of basal sauropod dinosaurs known from Middle Jurassic to Early Cretaceous deposits in Europe, North America, and Africa.

Vulcanodontidae

The Early Jurassic sauropod dinosaurs Zizhongosaurus, Barapasaurus, Tazoudasaurus, and Vulcanodon may form a natural group of basal sauropods called the Vulcanodontidae. Basal vulcanodonts include some of the earliest known examples of sauropods. The family-level name Vulcanodontidae was erected by M.R. Cooper in 1984. In 1995 Hunt et al. published the opinion that the family is synonymous with the Barapasauridae. One of the key morphological features specific to the family is an unusually narrow sacrum.

Zby

Zby is an extinct genus of turiasaurian sauropod dinosaur known from the Late Jurassic (late Kimmeridgian stage) of the Lourinhã Formation, central west Portugal. It contains a single species, Zby atlanticus. It is named after Georges Zbyszewski, who studied the geology and paleontology of Portugal.
