Chirostenotes

Gilmore 1924

Chirostenotes est un genre fossile de petits dinosaures à plumes de la famille des Caenagnathidae. Il a vécu au Canada, à la fin du Crétacé supérieur. Le genre est encore mal connu car ses restes fossiles sont peu nombreux et fragmentaires. Le genre est resté monotypique et la seule espèce fossile connue est l'espèce type Chirostenotes pergracilis.
