Hmm. I do recall Chatterjeea has an oddly ornithomimid-like pelvis...
Ornithomimid-like! Of all things! :-D
See Jalil 2002 (SVP) and Parrish 2003 (SVPCA).
Ah.
I suppose Polarornis is unlikely to be non-dinosaurian, though its gaviiform nature has been questioned.
There's still *Gobipipus*... assuming it has actually been described...
