Certainly:
_Borogovia_
_Saurornithoides_
_Sinornithoides_
_Tochisaurus_
unamed Mongolian troodontid

And probably:
_Ornithodesmus cluniculus_ (not to be confused with "Ornithodesmus"
        _latidens_, a pterosaur)
_Troodon? isfarensis_
indeterminate material from the Cedar Mountain Formation

And maybe:
"_Araucanoraptor_"
_Elopteryx_, which may be synonymous with _Bradycneme_ and _Heptasteornis_
_Koparion_
_Lisboasaurus_
_Paronychodon_
