What is "paraves"

Paraves is a branch-based clade defined to include all dinosaurs which are more closely related to birds than to oviraptorosaurs. Paravians comprises two major sub-groups: Avialae, including Jeholornis and modern birds, and the Deinonychosauria, which includes the dromaeosaurids and troodontids, which may or may not form a natural group.
