Re: Strange thoughts on PN - was Re: BAD vs. BADD



Dinsauria=(Megalos+Iguanodon)
Aves=(Archaeo+Passer)
Classicodinosauria (or whatever) = Dinosauria without Aves

just because this grouping is so useful...

Is it so useful?

Isn't it less useful than:

- primarily flightless dinosaurs
- primarily wingless dinosaurs
- primarily featherless dinosaurs
- Mesozoic dinosaurs
- non-neornithean dinosaurs
- extinct dinosaurs (now _that_ is paraphyletic!)

You could find more. You probably will.
