Right. Ignore all the features that make Opisthocoelicaudia a non-titanosaur
and just consider those that are similar to titanosaur features. Give the
same weight to the shape of an ulna as you would to a whole series of bifid
neural spines or to a whole series of opisthocoelous caudals. Anyone else
