Valid Synapomorphies or not?

[Steven Mahon <floridamahon@yahoo.com>]

 Hello Again,

I've done some research & have found lists of
synapomorphies that unite the following: Troodontidae,
Troodontidae + other groups, Ornithomimoidea (sensu
Sereno), Ornithomimoidea + other groups, & "Coeluria".

Troodontidae
1.most distal posterior serration forming tip of tooth
2.enlarged elongate maxillary fenatra
3.dentary dentaryfornina inside lateral groove
4.calcaneum lost
5.tongue-like extension of articular surface          
metatarsal III 
6.metatarsal IV most robust in pes

Troodontidae + other groups
7.lateral depression in braincase
8.fibula reduced to splint
9.arctometatarsus
10.maxilla broadly contacts naris
11.nasals narrow caudally
12.numerous teeth 
13.enlarged serrations
14.teeth w/ blood grooves
15.inter dental plates absent
16.no basisphenoid recess
17.inflated parasphenoid

Ornithomimoidea
18.dorsal premaxillary process dorsoventrally
flattened
19.orbital flange on prefrontal
20.maxillary & dentary teeth implanted in groove
21.flexor depression proximal to distal condyles on
proximal manual phalanges
22.paired flexor processes on manual phalanx I-1
23.dorsolateral tubercle on manual phalanx I-1
24.metacarpal-phalangeal joint of digit 1 w/
approximately 15 degrees maximum extension
25.metacarpal III at least 75% the width of metacarpal
II
26.metacarpals w/ 60-70% of shafts in contact
27.metacarpal I at least 60% the length of metacarpal
II
28.subnarial foramen absent
29.nasal anteroventral process absent

"Coeluria"
30.cervical epipophyses not overhanging the
postzygopophyses
31.posterior dorsal neural spines lower than long 

Heres what I need to know:
1. any others I'm missing
2. if any character is present in any other
genus/genera.


    Thanks in advance,
        Steven Mahon
