The Oviraptoridae is further divided into the small, short-armed, and crestless subfamily Ingeniinae, and the larger, crested, long-armed Oviraptorinae. However, some phylogenetic studies have suggested that many traditional members of the Caenagnathidae were more closely related to the crested oviraptorids.
Oviraptoridae is a group of bird-like, herbivorous and omnivorous maniraptoran dinosaurs. Oviraptorids are characterized by their toothless, parrot-like beaks and, in some cases, elaborate crests . They were generally small, measuring between one and two metres long in most cases, though some possible oviraptorids were enormous.

The describers' phylogenetic analysis places it as a derived member of the subfamily Heyuanninae in the family Oviraptoridae. It has been suggested that Oksoko represents a highly derived form in a series of oviraptorosaurs whose third digits have reduced over evolutionary time.
The traditional modes of reproduction include oviparity, taken to be the ancestral condition, traditionally where either unfertilised oocytes or fertilised eggs are spawned, and viviparity traditionally including any mechanism where young are born live, or where the development of the young is supported by either parent in or on any part of their body.
Oviraptor (/ ˈ oʊ v ɪ r æ p t ər /; lit. ' egg thief ') is a genus of oviraptorid dinosaur that lived in Asia during the Late Cretaceous period. The first remains were collected from the Djadokhta Formation of Mongolia in 1923 during a paleontological expedition led by Roy Chapman Andrews, and in the following year the genus and type species Oviraptor philoceratops were named by Henry ...
Brianne Tushaus has trapped between 150 and 200 feral and outdoor cats in the past year, taking them to the Animal Humane Society to be spayed or neutered for free and returning them to her south ...
Citipati was a large-bodied oviraptorid, with the largest individuals being emu-sized animals; it has been estimated at 2.5–2.9 m (8.2–9.5 ft) in length with a weight between 75–110 kg (165–243 lb), [21] [22] [23] and was one of the largest known oviraptorosaurs until the description of Gigantoraptor.
