I don't think I'll publish a phylogeny as stupid as the one I proposed... which is identical in its logic, construction, and merit to the reptiles. Just replace "sacrum covered with ribs" with "fur or feathers". The difference between the two: opinion. You think feathers don't belong in the reptilia because you don't feel like they belong, and someone else could just as well remove the turtles for equally subjective and absurd reasons. The difference, therefore, is actually historic. Generations ago, ignorant people felt like birds were different from reptiles, but people felt like turtles were not.
