Dzharatitanis (meaning "Dzharakuduk titan") is a genus of sauropod from the Bissekty Formation in Uzbekistan, dating to the Turonian age of the Late Cretaceous. The genus contains a single species, Dzharatitanis kingi, named after geologist Christopher King, who contributed to the Cretaceous geology of Asia. It is currently one of two known sauropods from the Bissekty Formation, alongside an indeterminate titanosaur.[1] In its original publication it was considered to be a member of Rebbachisauridae, but later papers considered it to be a titanosaur.[2]
Discovery and naming
The holotype was found in 1997 by Hans-Dieter Sues and David J. Ward during the URBAC (Uzbek/Russian/British/American/Canadian) expedition. It was classified as a titanosaur before being given a name on two occasions - firstly by Sues et al. (2015)[3] and then by Averianov and Sues (2017).[4] The genus Dzharatitanis was described in 2021 by Alexander Averianov and Hans-Dieter Sues. It was named after the Dzharakuduk locality in Uzbekistan and the titans in ancient Greek mythology. The genus was based on an anterior caudal vertebra (USNM 538127), likely representing the first caudal, that was originally described as belonging to an intermediate titanosaurian taxon.[1][3] The juvenile dorsal sauropod centrum USNM 538133 may also belong to this taxon.[1]

As observed in the original 2015 description of sauropod fossil material from Uzbekistan's Bissekty Formation, and reinforced by a later 2022 study, the Dzharatitanis holotype caudal vertebra is remarkably similar to those of the contemporary Asian sauropod Dongyangosaurus, which may have affinities to the Titanosauria.[3][5][6]
