Chirostenotes pergracilis was named from Greek ‘narrow-handed’ is a genus of oviraptorosaurian dinosaur from the late Cretaceous (about 76.5 million years ago) of Alberta, Canada. Chirostenotes was characterized by long arms ending in relatively straight claws, and long powerful legs. In life, the animal was about 6.6 ft. long.

In 2016 its estimated its length at was 8.2 ft. and its weight at 220 lbs., while the same year Molina-Pérez and Larramendi gave a length of 8.5 ft. and a weight of 88 lbs.

Chirostenotes pergracilis was probably an omnivore or herbivore, based on evidence from the beaks of related species like Anzu wyliei and Caenagnathus collinsi.

In 2005 Phil Senter and J. Michael Parrish published a study on the claw flange hand function of Chirostenotes pergracilis and found that its elongated second finger with its unusually straight claw may have been an adaptation to crevice probing. They suggested that Chirostenotes pergracilis may have fed on soft bodied prey that could be impaled by the second claw, such as grubs, as well as unarmored amphibians, reptiles, and mammals. However, if Chirostenotes pergracilis possessed the large primary feathers on its second finger that have been found in other oviraptorosaurs such as Caudipteryx, it would not have been able to engage in such behavior.

Chirostenotes pergracilis was characterized by a beak, long arms ending in powerful claws; long, slender toes and a tall, rounded cassowary like crest. Late Cretaceous Chirostenotes known from Canada and U.S.A. was probably an omnivore or herbivore. The third finger of the claw flange hand was longer than the first. The toe bones were also long and thin. The hands were suitable for collecting mollusks, other invertebrates, and eggs. The long specialized third finger may have been used to pry insects and other invertebrates from crevices in trees or streams.
