Here be there no dragons.

Evolutionary biologists: I'm trying to recall the concise explanation a professor gave in an evolution and ecology course about why dragons just plain did not exist.

I should have probably saved my notes from class but... I was trying to explain to someone why dragons, as they are popularly imagined (four legs + two wings), were not evolutionary possible? In terms of that number and arrangement of appendages being very unlikely, given that vertebrates, from bats to elephants to humans, kind of have similarish skeletal body plans? Anyway, I wasn't doing a very good job of explaining, and was forgetting how to use correct terminology ("convergent... uh... synapomorphies that... uh... wait, no...").
Could someone please throw me a bone here and say what I'm trying to say with appropriate evolutionary terms?
