Subject: My classification of coelurosaurs

     I think it was Scott who said he didn't know what I was talking abou=
when I said intermediate clades don't have to be formally named.  =

     Below is a good example, my preliminary classification of avetheropo=
posted on DML this morning.  Intermediate clades like avetheropods,
coelurosaurs, avialae, etc., are encoded, but not "formally" recognized i=
n my
cladisto-eclectic classifications (The Kinman System, 1994).  =

Dear All,
     I decided to begin seriously constructing a cladisto-eclectic
classification of Order Saurischiformes.  Below is my preliminary
classification of coelurosaurs, plus its immediate allosaurid sister grou=
p (so
it is really a classification of the avetheropod clade). =

     Please note that I recognize broader families (as traditionalists te=
nd to
do).  Perhaps the tyrannosaur implosion of genera will translate into a s=
implosion of family taxa as well (more like mine)?  In any case, comments=
             -----Ken Kinman
 Order Saurischiformes (in part)
      4   Allosauridae (=3D Carnosauria)
     5A   Ornitholestidae (possibly paraphyletic)
      B   Compsognathidae
      6   Tyrannosauridae
      ?   Coeluridae
      7   Ornithomimidae
      8   Therizinosauridae
      9   Caudipter(yg)idae
     _a_  Oviraptoridae
     10A  Alvarezsauridae
      B   Avimimidae
     11   Troodontidae
     12   Dromaeosauridae (=3D Deinonychosauria)
     13   Plesion _Rahonavis_
     14   {{Aves}}
******************************************  NOTES:  For those of you who
recognize a single clade for Therizinosauridae, Caudipteridae, and
Oviraptoridae---- you would simply change the 9 to 8B (and then renumber =
to 9-13).  The capital letters indicate subclades (the main clades are
numbered in the order they split off).   The coding symbol _a_ shows that=

Oviraptoridae is an exgroup from Caudipteridae.  You could combine them i=
an expanded holophyletic Oviraptoridae, but I wouldn't recommend this (be=
it could become doubly paraphyletic if the cladograms change significantl=
y). =

Also note that I only put in one plesion, but others may be added when th=
classification is completed.  And the {{Aves}} marker shows the cladistic=

placement of the exgroup Class Aves.  Sister group "nesting" is not sacri=
as in traditional eclectic classifications.  =
