Several other "Saurornithoides" species were named, though none of these is today seen as valid. In 1928, baron Franz Nopcsa coined "Saurornithoides sauvagei". However, this was the result of a printing error: he had planned to name a "Teinurosaurus sauvagei". In 1982, Kenneth Carpenter renamed "Stenonychosaurus inequalis" Sternberg 1932 into "Saurornithoides inequalis". Today this is usually seen as a junior synonym of "Troodon formosus". In 1991, George Olshevsky renamed "Pectinodon asiamericanus" Nesov 1985 into "Saurornithoides asiamericanus". In 1995 he made it a "Troodon asiaamericanus". In view of its provenance from the Cenomanian of Uzbekistan, it is usually seen as a different taxon from "Saurornithoides". In 2000, Olshevsky renamed "Troodon isfarensis" Nessov 1995 into "Saurornithoides isfarensis". In 2007, this was shown to have been a hadrosaurid fossil.
