anatomical data from Diamantinasaurus also rendered Nemegtosauridae paraphyletic, with Rapetosaurus falling out as a member of Saltasauridae closer to Isisaurus than to Nemegtosaurus. The cladistic analysis of Patagotitan recovered Tapuiasaurus as the sister taxon of Rapetosaurus and Isisaurus but not Nemegtosaurus. Nemegtosauridae was retained as a potentially useful clade of titanosaurs by Carballido and colleagues in 2022, who noted that it was either resolved as a small clade of titanosaurs, or an extensive group of taxa closer to Nemegtosaurus than Saltasaurus. Further work on the discovered postcrania was required to resolve the relationships of Nemegtosaurus and Opisthocoelicaudia, but it was preliminarily retained as a clade of saltasauroid that may end up as a synonym of Opisthocoelicaudiinae or even Lirainosaurinae.
