For what it's worth, Darren considers _Stenopelix_ to be
pachcephalosaurian.

I wonder if anyone can tell me where "Giraffatitan" has been published
as a genus?  Paul 1988, which creates the name, proposes it as a
subgenus of _Brachiosaurus_, but not as a genus.  It seems that people
have started to run with the idea of it as a separate genus, but I'd
like to see the reference for this.
