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 
smell a rat here??
