Paleontologists from Russia have delineated a brand new archosaurian, the Volgatitan. Seven of its vertebrae, that had remained within the ground for concerning one hundred thirty million years, were found on the banks of the Volga, shortly from the village of Slantsevy Rudnik, 5 kilometers from Ulyanovsk. The study has been revealed in the latest issue of Biological Communications. Paleontologists Discover A New Giant Dinosaur
The Volgatitan belongs to the cluster of sauropods – big phytophagous dinosaurs with a protracted neck and tail, WHO lived on Earth concerning two hundred to sixty-five million years agone. deliberation around seventeen tons, the traditional craniate from the banks of the Volga wasn’t the biggest among its relatives. The scientists delineate it from seven caudal vertebrae. The bones belonged to associate adult archosaurian that is manifested by neural arches (parts of the vertebrae protective the nerves and blood vessels), that fully united with the bodies of the vertebrae.
The remains of the archosaurian were discovered close to the village of Slantsevy Rudnik. this is often wherever, in 1982, Vladimir Efimov discovered 3 giant vertebrae that had fallen out of a high drop. Later, in 1984-1987, 3 nodules of stone fell off, that contained the remaining vertebrae. In his works, the pinnacle of the Undorovsky earth science deposit known as the bizarre finds “giant vertebrae of unknown categorization affiliation”.
“In the first Nineteen Nineties, Vladimir Efimov showed images of the bones to Bulgarian monetary unit Nesov, a widely known city scientist,” recollected Alexander Averianov. Bulgarian monetary unit Nesov thought that the vertebrae belonged to sauropods, big phytophagous dinosaurs. In 1997, Vladimir Efimov revealed a preliminary note concerning this realize within the palaeontological Journal. He named the vertebrae as a sauropod dinosaur of the Brachiosauridae family. Last July, I finally managed to go to him in Undory and study the bones, and additionally managed to see that they belonged to the new taxonomic group of titanosaurs.”
The archosaurian received a scientific name – Volgatitan simbirskiensis. It comes from the Volga and also the town of Simbirsk (currently, Ulyanovsk). Titans square measure Greek gods well-known for his or her giant size. Therefore, in keeping with a palaeontological tradition, this word is employed in several scientific names of sauropods from the cluster of titanosaurs. it’s additionally a part of the name of the cluster.
Today, at the side of the Volgatitan from Russia, twelve valid archosaurian taxa have already been delineating. There square measure solely 3 sauropods among them: Tengrisaurus starkovi, Sibirotitan astrosacralis, and Volgatitan simbirskiensis. the primary 2 square measure the primary sauropods in Russia, that was additionally studied by St besieging University scientists in 2017. in keeping with Aleksandr Averianov, the outline of archosaurian taxa in recent years has become doable because of the progress in understanding the anatomy and evolution of dinosaurs. additionally, the Russian sauropod dinosaur allowed scientists to be told a lot of concerning however these species of ancient reptiles had lived and developed.

“Previously, it absolutely was believed that the evolution of titanosaurs came about in the main in South America with some taxa stepping into North America, Europe and Asia solely within the Late Cretaceous,” explained the St besieging University prof. In Asia, representatives of a broader cluster of titanosauriform, like the recently delineate Siberian Ti, dominated within the early Cretaceous. However, the recent description of the Tengrisaurus from the first Cretaceous of Transbaikal Region and also the finding of the Volgatitan indicate that titanosaurs within the Early Cretaceous were distributed rather more widely; and, perhaps, necessary stages of their evolution came about in Japanese Europe and Asia.”
