Trogons and Grebes

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

New papers in the new July issue of _Ibis_ include fossils and clades:

  Mayr. G. 2005. New trogons from the early Tertiary of Germany. _Ibis_
    147(3):512-518.

Abstract:
  "A new trogon (Aves, Trogoniformes), *Primotrogon? pumilio* sp. nov., is
   described from the Middle Eocene (49 Ma) of Messel in Germany. It is the
   first articulated skeleton of an Eocene trogon, of which only very few
   fragmentary remains were hitherto known. It is also the earliest complete
   skeleton of a trogon, exceeding previous finds (*Primotrogon wintersteini*
   Mayr 1999) by at least 15 million years. An isolated wing of a trogon is
   further identified from the early Oligocene (about 30-34 Ma) of the fossil
   site Frauenweiler in Germany. *Primotrogon? pumilio* and all other
   sufficiently well-preserved early Tertiary trogons appear to be stem group
   representatives of the Trogoniformes, corresponding with molecular clock
data
   indicating a mid-Tertiary origin of crown group Trogoniformes."

  Gangster, G. 2005. A name for the flamingo--grebe clade. _Ibis_
    147(3):612-615.
