Oviraptorinae is a subfamily of bird-like maniraptora

Maniraptora

Maniraptora is a clade of coelurosaurian dinosaurs which includes the birds and the dinosaurs that were more closely related to them than to Ornithomimus velox. It contains the major subgroups Avialae, Deinonychosauria, Oviraptorosauria and Therizinosauria. Ornitholestes and the Alvarezsauroidea...

Oviraptoridae

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...

Classification and species

The classification of the oviraptorids has been controversial. The Oviraptoridae was traditionally divided into the small, short-armed, and crestless subfamily "Ingeniinae" (the name was preoccupied by an invertebrate group), and the larger, crested, long-armed Oviraptorinae. However, later phylogenetic studies showed that many traditional members of the Caenagnathidae were in fact more closely related to the crested oviraptorids. Because Caenagnathus

itself is no longer considered part of this group, the subfamiliy is usually now termed the Elmisaurinae. The Ingeniines are now typically included with the oviraptorines to reflect this new basic division in forms. The taxonomy below follows the one presented by Thomas Holtz, Jr. in 2010.
