Scientists from Russia have portrayed another dinosaur, the Volgatitan. Seven of its vertebrae, which had stayed in the ground for around 130 million years, were found on the banks of the Volga, not a long way from the town of Slantsevy Rudnik, five kilometers from Ulyanovsk.
The Volgatitan has a place with the gathering of sauropods – goliath herbivorous dinosaurs with a long neck and tail, who lived on Earth around 200 to 65 million years prior. Weighing around 17 tons, the antiquated reptile from the banks of the Volga was not the biggest among its relatives. The researchers depicted it from seven caudal vertebrae. The bones had a place with a grown-up dinosaur which is showed by neural curves (parts of the vertebrae securing the nerves and veins), which totally converged with the assemblages of the vertebrae.
The remaining parts of the dinosaur were found close to the town of Slantsevy Rudnik. This is the place, in 1982, Vladimir Efimov found three substantial vertebrae that had dropped out of a high precipice. Afterward, in 1984-1987, three knobs of limestone tumbled off, which contained the rest of the vertebrae. In his works, the leader of the Undorovsky Paleontology Museum called the strange discovers “mammoth vertebrae of obscure taxonomic association”.
The dinosaur got a scientific name – Volgatitan simbirskiensis. It originates from the Volga River and the city of Simbirsk (right now, Ulyanovsk). Today, alongside the Volgatitan from Russia, 12 substantial dinosaur taxa have just been depicted. There are just three sauropods among them: Tengrisaurus starkovi, Sibirotitan astrosacralis and Volgatitan simbirskiensis. The initial two are the main sauropods in Russia, which were additionally examined by St Petersburg University researchers in 2017. As indicated by Aleksandr Averianov, the depiction of dinosaur taxa lately has turned out to be conceivable because of the advancement in understanding the life structures and phylogeny of dinosaurs. What’s more, the Russian sauropod enabled researchers to take in more about how these types of antiquated reptiles had lived and created.
“Beforehand, it was trusted that the advancement of titanosaurs occurred predominantly in South America with some taxa moving into North America, Europe and Asia just in the Late Cretaceous,” clarified the St Petersburg University professor. In Asia, memebrs of a more extensive group of titanosauriform, for example, the as of late portrayed Siberian titanium, commanded in the early Cretaceous. Nonetheless, the ongoing portrayal of the Tengrisaurus from the Early Cretaceous of Transbaikal Region and the finding of the Volgatitan show that titanosaurs in the Early Cretaceous were dispersed substantially more broadly; and, maybe, critical phases of their development occurred in Eastern Europe and Asia.”
