this is an AWESOME creature... I like how it doesn't have to have scales, horns, fangs, a tail, or to overcompensate in any way to be just as fascinating... in fact, it's the strange lack of features that gives this such an eerie humanness... creepy, but fascinating. I want to meet one, LOL.
even when looking at illustrations of real Azhdarchids, I was astonished by how large their heads were compared to the rest of the body, and how tall they could grow compared to humans. It's hard to believe that they never evolved to super-intelligence :/
I've always imagine sentient pterosaurs as volant. As for other flying sophonts, crows and parrots aren't terribly hard to imagine, and would certainly work as still volant
I'd assume they'd still use the front paws, like your flightless one. With pterosaur wing design, it should be possible to get manipulative ability and flight out of the same limb (admittedly, not at the same time).
It's hard to believe that they never evolved to super-intelligence :/
What do they eat? Are they oviparous or viviparous? What's their sexual dimorphism like?
I wonder: What about a sapient flying azhdarchid?
Flying sophonrs: A tricky one, but by no means impossible. How would they manipulate objects, though? Feet? Beaks?
