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 {{dinogloss|caudal vertebrae}} 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.{{cite journal |url=https://biocomm.spbu.ru/article/view/1077/2900 |title=The oldest titanosaurian sauropod of the Northern Hemisphere |journal=Biological Communications |last1=Averianov |first1=Alexander |last2=Efimov |first2=Vladimir |year=2018 |volume=63 |issue=6 |pages=145–162 |doi=10.21638/spbu03.2018.301|doi-access=free |hdl=11701/15099 |hdl-access=free }} It was first described in November 2018 by Russian palaeontologists Alexander Averianov and Vladimir Efimov.{{cite web |title=Russian scientists discover new giant herbivorous dinosaur Volgatitan |url=https://www.indiatoday.in/education-today/gk-current-affairs/story/russian-scientists-discover-new-giant-herbivorous-dinosaur-volgatitan-1406127-2018-12-10 |date=10 December 2018 |website=India Today |access-date=16 December 2018 |language=en}} It is estimated to have weighed about {{convert|17.3|MT|ST}}.
