There are also several _published_ refs which have concrete data to
support their formation and can be verified at:
Holtz, T.R., Jr. 2000. A new phylogeny of the carnivorous dinosaurs.
_GAIA_ 15: 5-61.
Xu X.; Zhou Z.-g.; Wang X.-l.; Kuang X.-w.; Zhang F.-c.; and Du X.k. 2003.
Four-winged dinosaurs from China. _Nature_ 421: 335-340.
Xu X.; Norell, M.A.; Wang X.-l.; Makovicky, P.J.; and Wu X.-c. 2002. A
basal troodontid from the Early Cretaceous of China. Nature 415: 780-784.
Hwang, S.H.; Norell, M.A.; Ji Q.; and Gao K.-q. 2004. A large
compsognathid from the Early Cretaceous Yixian Formation of China.
_Journal of Systematic Palaeontology_ 2(1): 13-30.
These are the most current analyses up to this date, and cover
everything from the origin of birds into the origin of Coelurosaurs; the
Xu et al. and Hwang et al. papers cover the nature of maniraptoran
phylogeny much more extensively than does Holtz, however Holtz covers
general theropod phylogeny and more basal than coelurosaur phylogeny much
more extensively, and is just as important to maniraptoran phylogeny than
a maniraptorans-only or -enforced study.

Little steps are often the hardest to take. We are too used to making leaps
in the face of adversity, that a simple skip is so hard to do. We should all
learn to walk soft, walk small, see the world around us rather than zoom by it.
