[Taxacom] Class MAMMALIA (1994 ---> 2007)

[Ken Kinman]

Dear All,
      I've been wanting to update my ordinal classification of Class 
Mammalia (of 1994), but it has been a frustrating process (especially 
placing the various extinct Orders of Eutheria).  Still don't have all the 
literature I would like, but lately have had more people asking about my 
mammal classification, so here's how it presently looks.  Coding of the 
eutherian Orders in particular has changed quite a bit due to all of the 
molecular data that has come out in the past 13 years.  Adding the three 
subclass divisions also makes it easier to use and more informative.

     There are obviously some new fossil taxa, and the paraphyletic Order 
Symmetrodontiformes has been split.  Also some consolidation (lumping), such 
as Order Meridiunguliformes (instead of several separate extinct Orders), 
and also one Order Cetiformes instead of three separate Orders for whales.  
However, I will NOT lump the whales into the mother taxon 
Artiodactyliformes---any more than I would lump Aves into Reptilia---as it 
would destroy perfectly good anagenetic (divergence) information, not to 
mention utility, stability, and overall practicality.   The placement of 
bats (Chiropteriformes) is still controversial, but placement at the base of 
a Pegasoferae clade presently seems the best bet.  However, if bats are 
actually basal Scrotifera, then Pegasoferae collapses as a clade.  As always 
comments and suggestions are welcomed.

***********************************
  NOTES: Order Symmetrodontiformes split into Kuehneotheriiformes, 
Spalacotheriiformes, and Shuotheriiformes.  Shuotheriiformes may or may not 
clade with Monotremiformes (as Yinotheria sensu lato?).

      Major Eutherian Clades:
  Crown group Eutheria = Xenarthriformes, etc.
  Epitheria = Leptictiformes, etc.
  Boreoeutheria = Anagaliformes, etc.
  Laurasiatheria = Lipotyphliformes, etc.
  Scrotifera = Arctocyoniformes, etc.
  Pegasoferae = Chiropteriformes, etc.
  Zoomata = Perissodactyliformes, etc.

     Eutherian Subclades:
  Afrotheria = Macroscelidiformes to Sireniformes
  Euarchontoglires = Anagaliformes to Primatiformes
  Eparctocyona (s.s.) = Arctocyoniformes to Cetiformes
  Ferae = Cimolestiformes to Carnivoriformes
