"Caenagnathus" no longer exists as a valid genus name (having been replaced by "Chirostenotes"), but this "Asian variation" remains as one of the littlest oviraptors. It's also one of the most primitive, and some have suggested that its specialized toothed beak may have been used to catch fish in a semi-aquatic habitat, as I've restored it here. "Caenagnathasia" is only known from a few sets of jaws from Uzbekistan (the same time and place as Azhdarcho), so I took the liberty of restoring it with large, long-toed feet like modern wading birds.
