Volgatitan (meaning "Volga giant") is a genus oftitanosauriansauropoddinosaur from theEarly Cretaceous of theUlyanovsk Oblast,Russia. Thetype and only species isVolgatitan simbirskiensis, known from sevencaudal vertebrae from a single individual. It is the oldest known titanosaur from the northern hemisphere, and is considered important for being related to theLognkosauria, a group known only fromSouth America later in theLate Cretaceous.[1] It was firstdescribed in November 2018 by Russianpalaeontologists Alexander Averianov and Vladimir Efimov.[1][2] It is estimated to have weighed about 17.3 metric tons (19.1 short tons).[1]
Averianov and Efimov recoveredVolgatitan as alithostrotiantitanosaur. They found Lithostrotia to be divided into two main lineages, one containingSaltasauridae, the other containingLognkosauria, withVolgatitan belonging to the latter. The following cladogram follows their analysis.[1]
