addressing your point on membranes: For them to be able to be sensitive enough to hear the faint sound of a twig snapping in the treeline, logically from a considerable distance, away from the treeline, they would be unable to withstand a screech loud enough to literally physically hurt a predator in said treeline. there is no mute button for your own voice. otherwise, how would you know what you were saying? since any sound you make is resulted by vibrations inside your own body, there is no way to nullify it.
also, the predator would NOT react to it 'like a physical blow' as you said. This is reality, not the Godzilla universe.
Also consider, Gira, that almost every known example of a flying creature that has lost it's ability to fly, has an alternative high speed method of mobility to compensate. in penguins it's swimming. in ostritches, it's running. I'm fairly sure a land-bound Quetzalcoatlus would not have had such mobility. longer legs alone are not enough. like I said earlier, if you were to wrap a horse or giraffe's legs with fabric, it would barely be able to move, robbing it of it's primary defense against predators [even WITHOUT the physical limitations, and relying on size in addition to speed, Giraffes are on the menu of several African predators, most notably lions. now imagine if you had a 42 foot long, 16 foot tall, 7 ton lion. yeah. you just drove a whole species of animals to extinction. great job, mate. Darwin would be proud]
also, on average, flightless creatures evolving from flying ancestors start out small and grow larger AFTER adapting to terrestrial life. Terror Birds weren't always that size. their flying ancestors, even when they first lost their ability to fly, would've been the size of pigeons. so to think that Quetzalcoatlus was terrestrial is, at best, a half-baked theory relying on very little solid evidence to back it up. narrow wings do not equal lack of flight. in fact, narrow wings help when gliding. take a look at Gulls. or if you want, sailplanes. high aspect ratios assist considerably in flight.
also, you state they lived in semi-arid landscapes. do you know how much wind is kicked up in a plain with moderately high temperatures? the thermals and draft alone would, with the right anatomical features, lift Quetzalcoatlus with little trouble. it's the same reason that windmills these days are placed in plains.
My next response, if I'm responded to before then, will be in about 2 hours. at present I'm in College and have a lecture to attend.
