       A little known oviraptorid,‭ ‬Elmisaurus is based upon very few remains.‭ ‬Initially cited as a species of the North American Chirostenotes,‭ ‬it was quickly named as a distinct genus.‭ ‬Still,‭ ‬the Chirostenotes connection did not end there as in‭ ‬1989‭ ‬the palaeontologist Philip Currie established a second species,‭ ‬Elmisaurus elegans based upon oviraptorid fossils from North America.‭ ‬In‭ ‬1997‭ ‬Hans-Dieter Sues referred the fossils then belonging to Elmisaurus as actually belonging to Chirostenotes,‭ ‬thus establishing the second species of this genus,‭ ‬C.‭ ‬elegans.
