Caenagnathidae

Gigantoraptor () is a genus of large oviraptorosaurian dinosaur that lived in Asia during the Late Cretaceous period. It is known from the Iren Dabasu Formation of Inner Mongolia, where the first remains were found in 2005.

Chirostenotes ( ; named from Greek 'narrow-handed') is a genus of oviraptorosaurian dinosaur from the late Cretaceous (about 76.5–75 million years ago) of Alberta, Canada. The type species is Chirostenotes pergracilis.

Microvenator (meaning "small hunter") is a genus of oviraptorosaurian theropod dinosaur from the Early Cretaceous Cloverly Formation in what is now south central Montana. The holotype fossil is an incomplete skeleton, most likely a juvenile with a length of , and consequently, the adult size remains uncertain. Microvenator is primitive and may be the "sister taxon to all other oviraptorosaurs."

Caenagnathasia ('recent jaw from Asia') is a genus of small caenagnathid oviraptorosaurian theropod from the Late Cretaceous of Uzbekistan.

Elmisaurus (meaning "foot sole lizard") is an extinct genus of caenagnathid theropod dinosaur from the Late Cretaceous Nemegt Formation of Mongolia.

Caenagnathidae is a family of derived caenagnathoid dinosaurs from the Cretaceous of North America and Asia. They are a member of the Oviraptorosauria, and relatives of the Oviraptoridae. Like other oviraptorosaurs, caenagnathids had specialized beaks, long necks, and short tails, and would have been covered in feathers. The relationships of caenagnathids were long a puzzle. The family was originally named by Raymond Martin Sternberg in 1940 as a family of flightless birds. The discovery of skeletons of the related oviraptorids revealed that they were in fact non-avian theropods, and the disco

Caenagnathus ('recent jaw') is a genus of caenagnathid oviraptorosaurian dinosaur from the late Cretaceous period (Campanian stage, about 75 million years ago). It is known from partial remains including lower jaws, a tail vertebra, hand bones, hind limbs, and pelvis, all found in the Dinosaur Park Formation of Alberta, Canada.

Apatoraptor (meaning "deceptive thief") is a genus of caenagnathid dinosaur which contains a single species, A. pennatus. The only known specimen was discovered in the Campanian-aged Horseshoe Canyon Formation of Alberta.

Ojoraptorsaurus is a dubious genus of oviraptorosaurian dinosaur from the late Cretaceous. Ojoraptorsaurus is only known from pubic bones found at the Naashoibito Member of the Ojo Alamo Formation dating to the late Maastrichtian, about 66 million years ago. It was first named by Robert M. Sullivan, Steven E. Jasinski and Mark P.A. van Tomme in 2011 and the type species is Ojoraptorsaurus boerei. The generic name combines a reference to the formation with a Latin raptor, "plunderer", and a Latinised Greek saurus, "lizard". The specific name honours oceanographer Arjan Boeré who found the speci

Epichirostenotes (meaning "above Chirostenotes", because it lived after the latter genus) is a genus of oviraptorosaurian dinosaur from the Late Cretaceous. Epichirostenotes is known from an incomplete skeleton found in 1923 at the Horseshoe Canyon Formation, in strata dated to about 72 million years ago. It was first named by Robert M. Sullivan, Steven E. Jasinski and Mark P.A. van Tomme in 2011 and the type species is Epichirostenotes curriei. Its holotype, ROM 43250, had been assigned to Chirostenotes pergracilis by Hans-Dieter Sues in 1997.

Hagryphus (meaning "Ha's griffin") is a monospecific genus of caenagnathid dinosaur from southern Utah that lived during the Late Cretaceous (upper Campanian stage, 75.95 Ma) in what is now the Kaiparowits Formation of the Grand Staircase–Escalante National Monument. The type and only species, Hagryphus giganteus, is known only from an incomplete but articulated left manus and the distal portion of the left radius. It was named in 2005 by Lindsay E. Zanno and Scott D. Sampson. Hagryphus has an estimated length of 2.4–3 metres (8–10 feet) and weight of 50 kilograms (110 lbs).

Citipes () is an extinct genus of caenagnathid theropod from the Late Cretaceous Dinosaur Park Formation in Alberta, Canada. The genus contains only one species, the type species, C. elegans. The generic name of Citipes is Latin for "fleet-footed", and the specific epithet "elegans" is Latin for "elegant". The type specimen of Citipes has a convoluted taxonomic history, and has been previously assigned to the genera Ornithomimus, Macrophalangia, Elmisaurus, Chirostenotes, and Leptorhynchos before being given its own genus in 2020. ==Discovery and naming== ===Initial discovery=== thumb|left|An

Beibeilong (Chinese: , ) is a genus of large caenagnathid dinosaurs that lived in China during the Late Cretaceous epoch, about 96 million to 88 million years ago. The genus contains a single species, Beibeilong sinensis. The species was named and described in 2017 through analysis of an embryonic skeleton (nicknamed Baby Louie) and partial nest with large eggs that were discovered in the Gaogou Formation of China (Henan Province) between 1992 and 1993.

Anomalipes (meaning "unusual foot") is an extinct genus of caenagnathid oviraptorosaurian dinosaurs known from the Late Cretaceous (Campanian age) Wangshi Group of China. The genus contains a single species, Anomalipes zhaoi, known from a partial hindlimb.

Eoneophron (meaning "dawn Neophron") is an extinct genus of caenagnathid theropod dinosaur from the Late Cretaceous Hell Creek Formation of South Dakota, US. The genus contains a single species, E. infernalis, known from a partial hindlimb.
