One interesting aspect of the cladogram provided is the apparently improper
application of Avialae. the authors exclude Caudipteryx from Avialae,
placing it with the latter taxon in a new, "unnamed", presumably stem-based,
taxon. As I currently understand Avialae, it is defined as (approximately):
"Modern birds [ugh!], and all taxa more closely related to modern birds than
to deinonychosaurs." If the tree topology is (Velociraptorinae,
Protarchaeopteryx, (Caudipteryx, Aves)), Caudipteryx is an Avialan, and the
"unnamed taxon" is Avialae. Hmm...
