There is already a debate about whether some azhdarchids were flightless, and you can imagine a world where islands, such as Madagascar, Mauritius and New Zealand, are dominated by strange terrestrial pterosaurs, much as in our timeline they were once the province of flightless elephant birds, dodos and giant moas.
