I keep forgetting: there are no more titanosaurids, only saltasaurids (and
andesaurids, etc.). Titanosaurus is finally (as I opined way back in 1978 in M
esozoic Meanderings #1 when I created the replacement name
Antarctosauridae--whose type genus no longer seems to have much to do with
"titanosaurs") acknowledged to be a nomen dubium and thus so is the family
name Titanosauridae, of which Titanosaurus is the type genus. A pair of
procoelous caudal vertebrae (syntype specimens of Titanosaurus indicus) is
just not enough material with which one might distinguish the various genera
in the family.
