About
Caenagnathidae - meaning "recent jaws" - is a family within Oviraptorosauria that was coined by Raymond Mckee Sternberg in 1940 and anchored by Caenagnathus - a "flightless bird" since proven to be Chirostenotes. And then it wasn't again.

The flightless caenagnathids are sisters of the oviraptorids and share a similar gereral body plan; long arms and legs, fused ankles, long necks, short tails, and fancy head crests, though they are more lightly-built with longer and more shallow jaws riddled with air-filled hollows and a series of ridges and toothlike processes.
Etymology
Caenagnathidae is derived from the Greek "kaine" (recent, new") and "gnathos" (jaws), and the Latin "idae" (family).
