That isn't what I said (or implied) at all. The features that make
_Opisthocelicaudia_ a titanosaur far outweigh alternative phylogenetic
scenarios. Where do you put this genus, George? And on what basis do you
make your assignment - as a result of a phylogenetic analysis (which
requires a lot of time and effort), or through a simple matter of "oh it
just feels right"?

What are you suggesting: That each caudal be coded separately? Can you see
how absurd this suggestion is? Do we therefore code each tooth of a
spinosaurid separately; or each wing feather of an _Archaeopteryx_; or each
plate of a stegosaur? Please, you can't possibly be serious.

Yes. And I think I know where the odor's coming from.
