Comments
Caenagnathoidea has precendence over Oviraptoroidea (Sereno 1999a), even though the genus Caenagnathus has been reduced to a junior synonym of Chirostenotes (Sues 1997). The active definition, which uses the genus Chirostenotes and species as specifiers, is a first-order revision of the initial definition proposed in Sereno (1999b).
