>From Sereno (1998 N. Jb. Geol. Palaont. Abh. 210: 41-83):
Saltasauridae = Opisthoceolicaudinae + Saltasaurinae.  (a Node-Stem Triplet,
or NST in Sereno's terminology).
p. 72: "Although not based on diversity, morphology or tradition, a
saltasaurid NST stabilizes the higher taxonomy of derived titanosaurs, and
supplants use of the taxon "Titanosauridae," which is not based on a valid
genus".
