metadata.name: dc.description.abstract
metadata.value: Volgatitan simbirskiensis, gen. et sp. nov., is described based on a series of anterior
  and middle caudal vertebrae from a single individual discovered in the Lower
  Cretaceous (upper Hauterivian, Speetoniceras versicolor ammonite Zone) marine
  deposits at Slantsevy Rudnik vertebrate locality near Ulyanovsk City, Russia.
  The new taxon is characterized by strongly procoelous anterior and middle
  caudal vertebrae, a long centrum of the first caudal vertebra, a strong ventral
  ridge in the anterior and middle caudal vertebrae, a neural arch positioned at
  the anterior half of the centrum, hyposphene-hypantrum articulation in the
  anterior caudal vertebrae, and somphospondylous bone texture. Phylogenetic
  analysis places the new taxon as a lithostrotian titanosaur, a basal member of
  the lineage leading to the Lognkosauria. This lineage previously contained only
  South American taxa with body mass reaching 60–70 tons. Volgatitan gen. nov.
  is the first European and the geologically oldest representative of this lineage.
  Its body mass is estimated as 17.3 tons. Discovery of Volgatitan gen. nov. suggests
  that the lithostrotian lineage leading to the Lognkosauria had a wider distribution
  in the Early Cretaceous and became extinct everywhere except South
  America by the end of the Early Cretaceous.
