Caenagnathid Species

["Jaime A. Headden" <qilongia@yahoo.com>]

Just a note:

  Despite what Sues (1998) and Varricchio (2001) wrote, and their reasons,
*Elmisaurus elegans* cannot, on present data, be referred to
*Chirostenotes,* much less a taxon based on an articular with
retroarticular of the surangular fused to it. The articular may very well
belong to *Elmisaurus* but not *Chirostenotes*, or to neither. Present
data does not allow us to evidence any referral, and the authors'
referrals are thereby unsupportable.

  Caenagnathidae Sternberg, 1940
    = Elmisauridae Osmólska, 1981
    Chirostenotes Sternberg, 1924
      = Macrophalangia Sternberg, 1932
      = Caenagnathus Sternberg, 1940
      C. pergracilis Sternberg, 1924 [type species]
        = M. canadensis Sternberg, 1932
        = C. collinsi Sternberg, 1940
      C. sternbergi Cracraft, 1972
    Elmisaurus Osmólska, 1981
      = "Ornithomimus" sensu Parks, 1933
      E. rarus Osmólska, 1981 [type species]
      E. elegans (Parks, 1933) Currie, 1988
        = C. elegans (Parks, 1933) Sues, 1998

  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.
