a parsimony-based analysis, an implied-weights analysis to optimize for homologous (i.e., derived from a shared ancestor) features, and a Bayesian (likelihood-based) analysis to account for the age of each specimen. All of their analyses recovered Klamelisaurus as part of a group of Middle-to-Late Jurassic sauropods that also included Mamenchisaurus, Chuanjiesaurus, Analong (as a referred specimen of Chuanjiesaurus), Wamweracaudia, Qijianglong, a specimen from Thailand (the Phu Kradung taxon), and a specimen from Xinjiang (the Shishugou cervicodorsal vertebrae). They termed these the "core Mamenchisaurus-like taxa". The parsimony-based and implied-weights analyses for the Carballido dataset found Klamelisaurus close to the Phu Kradung and Shishugou specimens, as well as M. youngi; the Bayesian analysis found M. constructus and M. hochuanensis closer than the latter two. The parsimony-based analysis for the Gonzàlez Riga dataset found Klamelisaurus close to M. youngi, M. hochuanensis, and Qijianglong; and the implied-weights and Bayesian analyses found it close to the Phu Kradung and Shishugou specimens, with the latter also including Chuanjiesaurus, M. constructus, and Euhelopus. Nearly all of their analyses found the "core Mamenchisaurus-like taxa" to be closely related to Euhelopus, Daxiatitan, and Dongbeititan, traditionally considered part of the more derived Macronaria. They recovered this wider group — which they termed the Euhelopodidae — outside of the Neosauropoda; the implied-weights analysis on the Carballido dataset placed it as an early-diverging macronarian lineage, also including Bellusaurus, while the implied-weights analysis on the Gonzàlez Riga dataset found Euhelopus among macronarians as a somphospondyl (in which case they called the group Mamenchisauridae). For all analyses, the support (or "likelihood") values for groupings within the Euhelopodidae were low. They considered the results of the implied-weights and Bayesian analyses of the Gonzàlez Riga dataset to be most favorable; still, the results of the two analyses differed profoundly. Thus, they highlighted a need for further redescriptions and revisions of these sauropods (particularly Mamenchisaurus and Omeisaurus) as well as the development of more distinguishing characteristics. Below, two phylogenetic trees show the internal relationships of Euhelopodidae/Mamenchisauridae in the two analyses Moore and colleagues deemed most favorable, the implied-weights and Bayesian analyses of the Gonzàlez Riga dataset.
