Amniota to Mammalia in four easy steps

[John Conway <john_conway@mac.com>]

I need to construct a cladogram (aimed at children) that encompasses the 
Amniota and gets to the level of Mammalia. Unfortunately, it needs to be 
done with just four nodes/stems. Obviously, I am going to have to leave 
off a lot, but my synapsid knowledge being what it is, I am at a 
complete loss.

Any help with synapsid phylogeny would be greatly appreciated, as would 
any suggestions on how to construct the abbreviated cladogram.


Strange that a Google search "synapsid cladograms" gets 50 hits, while 
the search "dinosaur cladograms" gets 1540.
