Aviae, Neornithia, and Passeria, Flying ancestor Pokemon

This is a fun idea where I try to design hypothetical common ancestors to a bunch of Pokemon, based on in-game egg groups.
Here are my idea for flying group ancestors. I did a range of designs this time, as the group is quite a bit bigger than previous ones I've done. Left is Aviae Prota, which is an ancestor to all in the group, and is more dino-like in appearence, being related to some dragon Pokemon.
Middle is Neornithia, ancestor to all existing bird Pokemon, and closely related to the extinct Fossil Pokemon, Archen.
Right is Passeria, ancestor to the 'Route 1 bird' archetype, among others.
