Jinfengopteryginae is a

Jinfengopterygines were relatively small sized troodontids ranging from about 0.5–2 m (1.8–6.6 ft),[1]^[2] and like other troodontids had a pair of sickle claws on each foot. These animals were feathered, as most troodontids presumably were, as shown in the type species, with typical feathering around the body an neck and especially long, vaned feathers spanning the tail. Studies on these animals' flight capabilities have determined that they would be approximately as proficient as Microraptor and Rahonavis.^[3] Although most other troodontids are believed to be primarily carnivorous, specimens of this subfamily show potential omnivory, being what are possibly plant seeds in the gut of Jinfengopteryx, although these have also been interpreted to be developing eggs or pennaceous follicles.^[4] However, omnivory in troodontids is not unheard of, as studies on jaw morphology in Troodon suggest.^[5]
