Volgatitan
''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. Classification Amerianov and Efimov recovered ''Volgatitan'' as a lithostrotian titanosaur. They found Lithostrotia to be divided into two main lineages, one containing Saltasauridae, the other containing Lognkosauria Lognkosauria is a clade of giant long-necked sauropod dinosaurs within the clade Titanosauria. It includes some of the largest and heaviest dinosaurs known. Description Lognkosaurians can be distinguished f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tengrisaurus
''Tengrisaurus'' (meaning "Tengri lizard") is a genus of lithostrotian sauropod, from the Early Cretaceous (Barremian-Aptian) Murtoi Formation, Russia. It was described in 2017 by Averianov & Skutschas. The type species is ''T. starkovi''. New remains were described in 2021 by Averianov, Sizov & Skutschas. Description ''Tengrisaurus starkovi'' is based on three caudal vertebrae. The genus is characterized by strongly procoelous anterior and middle caudal vertebrae, with strongly developed pre-epipophyses, highly pneumatic neural spine, and solid bone structure of the centrum. Classification Amerianov and Efimov (2018) recovered ''Tengrisaurus'' as a lithostrotian titanosaur. They found Lithostrotia to be divided into two main lineages, one containing Saltasauridae, the other containing Lognkosauria Lognkosauria is a clade of giant long-necked sauropod dinosaurs within the clade Titanosauria.

Lithostrotia
Lithostrotia is a clade of derived titanosaur sauropods that lived during the Early Cretaceous and Late Cretaceous. The group was defined by Upchurch ''et al.'' in 2004 as the most recent common ancestor of '' Malawisaurus'' and '' Saltasaurus'' and all the descendants of that ancestor. Lithostrotia is derived from the Ancient Greek , meaning "inlaid with stones", referring to the fact that many known lithostrotians are preserved with osteoderms. However, osteoderms are not a distinguishing feature of the group, as the two noted by Unchurch ''et al.'' include caudal vertebrae with strongly concave front faces (procoely), although the farthest vertebrae are not procoelous. History of research In 1895, Richard Lydekker named the family Titanosauridae to summarize sauropods with procoelous (concave on the front) caudal vertebrae. The name Titanosauridae has since been widely used, and was defined by Salgado and colleagues (1997), Gonzalaz-Riga (2003), and Salgado (2003) as a node- ...

Malawisaurus
''Malawisaurus'' (meaning "Malawi lizard") is an extinct genus of titanosaurian sauropod dinosaur. It is known from the Dinosaur Beds of northern Malawi, which probably date to the Aptian stage of the Early Cretaceous. The type species is ''M. dixeyi'' and the specific name honours Frederick Augustus Dixey. Discovery and naming ''Malawisaurus dixeyi'' was originally described in 1928 by Sidney H. Haughton as a species of '' Gigantosaurus'' (an invalid name for the diplodocid currently known as '' Tornieria''). Haughton considered it closely related to the species ''G. robustus'' (later the type species of '' Janenschia''). The holotype was discovered in the " Dinosaur Beds" of Malawi (then known as the Nyasaland Protectorate), which are usually considered to be of Barremian-Aptian age based on K–Ar dating, though they have also been suggested to be Late Cretaceous in age based on the vertebrate assemblage, and possibly also the Lupata Group. In 1993 it was placed in the n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossils Of Russia
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ...

Cretaceous Russia
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth by th ...

Rinconsaurus
''Rinconsaurus'' is a genus of titanosaur sauropod dinosaur from the Late Cretaceous in what is now Argentina. The type species, ''Rinconsaurus caudamirus'', was described by Calvo and Riga in 2003, and is based on three partial skeletons. Description Like all sauropods, ''Rinconsaurus'' was a large long-necked quadrupedal animal, with a long, whip-like tail and four pillar-like legs. ''Rinconsaurus'' was an unusually slender sauropod. Although fossil discoveries are incomplete, and no complete necks or heads have been found, fully grown ''Rinconsaurus'' are estimated to have been 11 meters (36 ft) long and approximately 2.5 meters (8 ft) high at the shoulder. The body mass of ''Rinconsaurus'' has been estimated to be between 3.21 and 5.39 tonnes. Discovery and species Fossils of ''Rinconsaurus'' were discovered in 1997 by Gabriel Benítezin strata belonging to the Bajo de la Carpa Formation near Rincón de los Sauces, in the Neuquen province of Argentina. ...

Epachthosaurus
''Epachthosaurus'' (meaning "heavy lizard") was a genus of titanosaurian sauropod dinosaur from the Late Cretaceous. It was a basal lithostrotian titanosaur. Its fossils have been found in Central and Northern Patagonia in South America. Discovery and naming The type species, ''E. sciuttoi'', was described by Powell in 1990. The bones assigned to it by Powell in 1990 were, originally, assigned to '' Antarctosaurus sp.'', and then to '' Argyrosaurus superbus?'', before being named as a new taxon. The holotype specimen is MACN-CH 1317, which consists of an incomplete posterior dorsal vertebra. Another specimen, the paratype MACN-CH 18689, consists of a cast of six articulated caudal vertebrae, the partial sacrum, and a fragmentary pubic peduncle from the right ilium. A nearly complete specimen referred to ''Epachthosaurus'', UNPSJB-PV 920, was recovered during field research conducted as part of the project ''Los vertebrados de la Formación Bajo Barreal, Provincia de Chubut, P ...

Pitekunsaurus
''Pitekunsaurus'' is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous Anacleto Formation of Neuquén, Argentina. It was described by L. Filippi and A. Garrido in 2008. The type species is ''P. macayai''. The generic name is derived from Mapudungun ''pitekun'', meaning "to discover", the epitheton honours the discoverer, oil company explorer Luis Macaya, who found the fossil in April 2004. Classification ''Pitekunsaurus'' appears to be a genus of aeolosaurid, most closely related to the genera ''Gondwanatitan'' and ''Aeolosaurus''. Its braincase closely resembles that of the aeolosaurid ''Muyelensaurus'' as well as the titanosaurs ''incertae sedis'' '' Vahiny'' and ''Jainosaurus''.

Isisaurus
''Isisaurus'' (named after the Indian Statistical Institute) is a genus of titanosaurian dinosaur from the Late Cretaceous Lameta Formation of India. The genus contains a single species, ''Isisaurus colberti''. Discovery and Naming The type specimen of ''Isisaurus colberti'', ISI R 335/1-65, was originally described and named as '' Titanosaurus colberti'' by Sohan Lal Jain and Saswati Bandyopadhyay in 1997. The specific name honours Edwin Harris Colbert. In 2003, the fossils were designated as belonging to its own genus by Wilson and Upchurch. The generic name, "''Isisaurus''," combines a reference to the Indian Statistical Institute (ISI) with the Greek "saurus," meaning "lizard." It had a short, vertically directed neck and long forelimbs, making it considerably different from other sauropods. The humerus is 148 centimetres long. ''Isisaurus'' is known from better remains than many other titanosaurs that were known at the time of its description. Much of its postcra ...
