Most studies of diplodocid relationships have found it to contain two primary subgroups: [[Diplodocinae]] (containing those diplodocids more closely related to ''Diplodocus'' than to ''Apatosaurus'') and [[Apatosaurinae]] (diplodocids more closely related to ''Apatosaurus'' than to ''Diplodocus''). Originally, it was thought that ''Supersaurus'' was related to the long-necked diplodocid ''[[Barosaurus]]'', and therefore a member of the subfamily Diplodocinae, however, with the assignment of the more complete WDC DMJ-021 most later studies found ''Supersaurus'' to be a close relative of the familiar ''[[Apatosaurus]]'' in the group Apatosaurinae.<ref name=LHW07/> However, some later studies cast doubt on this paradigm. One comprehensive study of diplodocoid relationships published by Whitlock in 2011 found ''Apatosaurus'' itself to lie at the base of the diplodocid family tree, and other "apatosaurines", including ''Supersaurus'', to be progressively more closely related to ''Diplodocus'' (making them diplodocines).<ref name=whitlock2011>{{cite journal|last=Whitlock|first=John A.|year=2011|title=A phylogenetic analysis of Diplodocoidea (Saurischia: Sauropoda)|journal=Zoological Journal of the Linnean Society|volume=161|issue=4|pages=872–915|doi=10.1111/j.1096-3642.2010.00665.x|doi-access=free}}</ref>

In 2015, a specimen-level [[phylogenetic]] study of diplodocids found that ''[[Dinheirosaurus lourinhanensis]]'' grouped with ''Supersaurus''. The study considered that it should be a new species of ''Supersaurus'', in a new combination ''S. lourinhanensis''.<ref name="Tschopp, E. 2015">{{Cite journal |last1=Tschopp |first1=Emanuel |last2=Mateus |first2=Octávio |last3=Benson |first3=Roger B.
