Dinosaurs of Russia

Olorotitan is a monotypic genus of lambeosaurine duck-billed dinosaur, containing a single species, O. arharensis. It was among the last non-avian dinosaurs to go extinct during the Cretaceous–Paleogene extinction event, having lived from the middle to late Maastrichtian age of the Late Cretaceous period. The remains were found in the Udurchukan Formation beds of Kundur, Arkharinsky District, Amur Oblast, Eastern Russia, in the vicinity of the Amur River.

Amurosaurus (; "Amur lizard") is a genus of lambeosaurine hadrosaurid dinosaur found in Late Cretaceous (70 to 66 million years ago) deposits of what is now eastern Asia.

Known material in white Kileskus (meaning "lizard" in the Khakas language) is a genus of tyrannosauroid dinosaur known from partial remains found in Middle Jurassic (Bathonian stage) Itat Formation of Sharypovsky District, Krasnoyarsk Krai (Russia). Fossils recovered include the holotype maxilla, a premaxilla, a surangular, and a few bones from the hand and foot. Additional remains referred to the species include cervical and caudal vertebrae,

Nipponosaurus (meaning "Japanese lizard") is a lambeosaurine hadrosaur from sediments of the Yezo Group, in Sinegorsk on the island of Sakhalin, which was part of Japan at the time of the species' classification. The type and only species is N. sachalinensis, known only from a single juvenile specimen discovered in 1934 and named in 1936, by Takumi Nagao, with further material of the same individual found in 1937. Since then, the taxon has been largely ignored, and its validity has been doubted, with synonymy with other Asian hadrosaurs or status as a nomen dubium being suggested. Redescriptio

Kerberosaurus (meaning "Kerberos lizard") is a genus of saurolophine duckbill dinosaur from the late Maastrichtian-aged (Upper Cretaceous) Tsagayan Formation of Blagoveshchensk, Amur Region, Russia (dated to 66 million years ago). It is based on bonebed material including skull remains indicating that it was related to Saurolophus and Prosaurolophus.

Volgatitan (meaning "Volga giant") is a genus of titanosaurian sauropod dinosaur from the Early Cretaceous of the Ulyanovsk Oblast, Russia. The type and only species is Volgatitan simbirskiensis, known from seven from a single individual. It is the oldest known titanosaur from the northern hemisphere, and is considered important for being related to the Lognkosauria, a group known only from South America later in the Late Cretaceous. It was first described in November 2018 by Russian palaeontologists Alexander Averianov and Vladimir Efimov. It is estimated to have weighed about .

Arkharavia (meaning "Arkhara road") is a dubious genus of somphospondylan sauropod, although at least some of its remains probably belong to a hadrosaurid. It was discovered in the Udurchukan Formation in Russia and lived during the Late Cretaceous. It was described in 2010 by Alifanov and Bolotsky as the type species A. heterocoelica.

Sibirotitan ("Siberian titan") is a genus of somphospondyl sauropod from the Early Cretaceous (Barremian age) Ilek Formation of Russia. The type and only species is S. astrosacralis.

Kundurosaurus is an extinct genus of saurolophine hadrosaurid dinosaur known from the latest Cretaceous (probably late Maastrichtian stage) of Amur Region, Far Eastern Russia. It contains a single species, Kundurosaurus nagornyi.

Kiyacursor (meaning "Kiya River runner") is an extinct genus of noasaurid theropod dinosaur from the Early Cretaceous Ilek Formation of Russia. The genus contains a single species, K. longipes, known from a partial skeleton. Kiyacursor represents the first Early Cretaceous ceratosaur discovered in Asia, as well as the second non-avian theropod named from Russia, after Kileskus in 2010.

Tengrisaurus (meaning "Tengri lizard") is an extinct genus of titanosaurian sauropod dinosaur known from the Early Cretaceous (Valanginian) Murtoi Formation of Russia. The genus was described in 2017 by Averianov & Skutschas, containing a single species, Tengrisaurus starkovi, known from several isolated vertebrae. Despite being among the oldest named definitive titanosaurs, it is an anatomically derived member of the clade Colossosauria.
