"Sinovenator" (followup)
Dear All,
I'm correcting a couple of small typos in my classification post last
night. I will also take this opportunity to add "cf. Sinornithosaurus" to
my classification. I agree with Mickey that "Dromaeosauridae gen. & sp.
indet." is far too imprecise.
Also, here is an example of how I code polytomies. Troodontidae and
the two plesia are coded as a trichotomy, until I feel certain that one of
those plesia is more closely related to Troodontidae than the other (and
want to take another look at Koparion---whatever it is).
And finally, let me express how saddened I am that anyone would even
suggest basing clade names on feather characteristics (Avifilopluma,
Avipinna, Aviremigia, Aviplumosa). Although I do favor apomorphy-based
taxa, basing them on feathers is so nonsensical that I would think it would
demonstrate that my controversial Aves (sensu lato) is really not so radical
afterall. And remember that my apomorphy-based definition is not yet
finalized (the "true" semilunate may yet be shifted to the "supportive"
character list).
------ Cheers, Ken
