DZHARATITANIS

The fossil that would eventually become Dzharatitanis was described in 2015 by Sues, Averianov, Ridgely and Witmer and interpreted as the property of a titanosaurian sauropod, but although they noted its distinctive features and that it likely represented a previously unknown taxon, they considered a single vertebra insufficient grounds for naming a new dinosaur. By 2021, half of those authors had changed their mind, yet when the specimen was formally named it was instead assigned to Rebbachisauridae. That made Dzharatitanis both the first rebbachisaurid diplodocoid reported from Asia and among the youngest members of that lineage in the global record. Its recognition also marked the second sauropod group to be documented from Uzbekistan's Bissekty Formation, following bones and teeth from the same unit that had been assigned to an indeterminate member of Titanosauria.

After Amargatitanis, Dzharatitanis is the second instance of the rarely-used "-titanis" being applied to a diplodocoid that was previously identified as a titanosaur, but in this case, it might still be one. Several palaeontologists have inspected the sole bone of Dzharatitanis since its christening and concluded that the original titanosaurian interpretation may have been right after all — an irony given that Sues and Averianov themselves had argued most strongly for its titanosaurian affinities in 2017, finding striking similarities to Dongyangosaurus from Zhejiang and Baotianmansaurus from Henan.
