So I should code *Sinornithosaurus* as "?"?

Should I add a state 2: big denticles to characters 13 and 14 (or just 14?)
and give it to troodontids and segnosaurs? Or should I maybe refrain from
adding probable noise to my matrix as long as it is rather tiny (I know it's
bad science...)?

http://www.geol.umd.edu/~tholtz/G104/104Y2K/104Lec21.htm says that not only
tyrannosaurs but also ornithomimosaurs have "Incisor-like premaxillary teeth
for nipping". That was news to me; I looked it up in Glut's Encyclopedia and
found it confirmed, as well as that I coded ornithomimosaurs wrong for
characters 13 and 14 because *Pelecanimimus* teeth are unserrated like those
of *Archaeopteryx*. Incredible that I had forgotten such a thing... :.-( So
thanks for the link!!! Should I add another state to character 13 or a new
character?

May I already ask how *Dryptosaurus* came out as a tyrannosauroid? :-o
        I suppose it is still unknown whether it was arctometatarsal?
