Re: Segnosaurs ejected from AVES



Sorry Mickey, but I don't understand why you think this is such a "horrible" decision. According to Jaime, segnosaurs lack fully-capped metacarpals I and II (flexor-extensorly) and do not have the classic semilunate shape (as well as being unfused). This is not a "true" semilunate carpal block on several points.
Segnosaurs also lack the convex coracoid glenoid, and apparently have a primitive eggshell type (perhaps controversial?).
And I would have to agree that there are fewer enigmosaur synapomorphies than people on this list seem to think (at least synapomorphies that are exclusively enigmosaurian). I see too many homoplasy "red flags" waving around. Something just isn't right about this "enigmosaur" holophyly thing in my opinion. I just can't get around this. Sorry, but I simply don't see it.
