Strange. I've read that Marilia Fm., along with Adamantina Fm., are
correlated with Allen, Angostura Colorada and Los Alamitos Fms. on the basis
of the presence of the titanosaurid *Aeolosaurus*, and thus dated as Late
Campanian-Early Maastrichtian.

I have the pdf of the last one (though is in Portuguese), if someone is
interested.
