The present study provides a synthesis of the diversity and geographical distribution of Titanosauria (Dinosauria: Sauropoda) from Upper Cretaceous rocks of the Bauru Group in Brazil. There are currently ten valid species of titanosaurs described for the Bauru Group, some of which exhibit similarities to species found in Argentina. Among these species is the well-known clade Aeolosaurini, which is considered as endemic to South America. Members belonging to the Aeolosaurini clade remains have so far been found only in Argentina and Brazil. This faunal similarity helps in the interpretation of the paleogeographic distribution of these organisms, which reflects intense faunal interchange between these regions, thereby indicating a chrono-correlated geological age.

So what viable titanosaur family does Aeolosaurini belong to?

It was named as a subgroup of Saltasaurinae (Franco-Rosas et al., 2004), which was named as a subfamily of Titanosauridae (Powell, 1992). Though perhaps notably, Aeolosaurini was also never claimed to be a tribe despite its suffix, only being called "new taxon" and Spanish equivalents.  Not saying I agree Utetitaninae needed to be created under a higher family level group, but those are the facts about Aeolosaurini.
