Citipatiinae

Funston et al., 2020 Type genus Citipati

Its genera lived 83.6–66.0 million years ago Late Cretaceous

Late Cretaceous stages

Citipatiinae is a subfamily of oviraptorid dinosaurs, a group of small, bird-like, beaked maniraptoran theropods that lived during the Late Cretaceous of Asia. It contains Citipati and its close relatives, the larger, long-armed, crested oviraptorids that were traditionally lumped into the subfamily Oviraptorinae. Funston and colleagues (2020) named it after their analysis placed Oviraptor outside the group, which made the earlier name Oviraptorinae inappropriate. Its members are distinguished by tall midline cranial crests, comparable to those of a cassowary, together with relatively long hands that retain three functional fingers.

Diagnosis

Tall, well-developed bony cranial crest
Relatively long manus retaining three functional digits
Nasal region incorporated into a raised, pneumatic crest
