I'm sorry Charles, but these words cause me to drag myself from my lair and lay some science down. Pterosaurs were not dinosaurs. They're Pterosaurs, closely related Archosaurs, but not dinosaurs. Dinosaurs and pterosaurs are closer related than crocodiles and dinosaurs
However if you ever want to use a Quetzalcoatlus, which you should, I always highly recommend the work of pterosaur researcher
Mark Witton. They're basically giraffe-sized murder storks who's food is 'Anything smaller than them', plus we have fossil evidence they traveled in flocks.
