OK now,

Here's some more synapomorphies I found (some of them
are iffy tho').

51.endentulous maxilla (tooth from premaxilla or
dentary)
52.prominent hypophyses on cervicodorsals
53.sternum rectangular longitudinally, w/ ossified
keel

57.tympanic recess opens within columellar recess (not
paroccipital process)

59.caudal count less than 25-26
60.short, reduced caudal zygapophyses

Alvarezsauridae
61.sacrals procoelous
62.posterior synsacrals compresses, vental keel
present
63.stout ungual I, quadrangular posteriorly
64.pubic peduncle of ilium slender
65.common ancestor had flexible (procoelous) tail

Dromaeosauridae
66.T-shaped lacrimal, Y-shaped quadratojugal
67.neural spines of neck vertebrae large& erect
68.5 sacral vertebrae
69.tendon-like extensions of tail zygapophyses,
chevrons
70.paired sternal plates
71.pubis faces down & backward to parallel ischium
72.digit I pes reversed, parallel to other toes
73.distal articulation of metatarsal II & III
ginglymoid

Velociraptorines
74.dental serrations front much smaller than in back
75.second premaxilla largest

Therizinosauridae
76.external nares enlarged 
77.jugal embraces lateral temporal fenestra ventrally
78.about 40 teeth primitively, become larger
anteriorly
79.dorsal neural arches elevated anteriorly
80.manual unguals flatsided & deep
81.antdorsal rim of ilium everted
82.ventral pelvic elements strap like, rotated
posteriorly
83.metatarsus short secondary contact between
metatarsal I & ankle
84.pes I ungual largest

Oviraptoroidea
85.pneumatic cassowary-like creat often present
86.abbreviated, generally edentulous parrot-like beaks
87.elevated external nares
88.dentary symphasis fused
89.dentary bifurcates posteriorly, large external
mandibular fenestrum
90.tongue-in-groove sliding jaw articulation
91.infranarial process of premaxilla contacts nasal 
92.presacrals contain pleurocoels
93.cervicodorsals have hypophyses
94.5 sacrals

Caenagnathids
95.long beaks
96.manus digitII longer than III
97.manual digit II more gracile
98.arctometatarsus

Oviraptorids
99.short beaks
100.manus digits II & III robust & subequal length
101.proximal metatarsal III broad

Bullatosauria
102.long, low skull arched behind the orbits
103.bulbous parasphenoid
104.elongate cervicals w/ low neural spines
105.no pleurocoels on dorsal vertebrae

More's comin' too..... I think a lot of these are
invalid tell me what you think!
