A good reference to have on hand. Currie and Carpenter argue rather
strenuously that _Acro_ is an allosaurid and not a carcharodontosaurid,
though most of the character states they mention are also consistent, to my
mind, with a position for _Acro_ as a primitive carcharodontosaurid, more or
less intermediate in form between _Allo_ and the carcharodontosaurines
(_Giga_ and _Carcharo_). That is certainly what it looks like to me.
They do have a cladogram, but for an outgroup they use the highly derived
Abelisauridae rather than the more conservative _Ceratosaurus_ (or something
like _Torvosaurus_), which I would have preferred. I also disagreed with
some of their character polarities.
All in all, a good read, though.
