"Predicted giant flight velocities exceeded 90 kph and, in that 90 second flapping burst, giant azhdarchids would cover several kilometres - plenty of distance to seek areas of uplift such as deflected winds or thermals."
I have a small issue with this statement. 90kph for 90 seconds is only enough for a bit more than 2km of flight and probably even less since accelerating to this speed would take not be almost instantaneous either.

- ncmncm 8y ago2.25 km is a hell of a long way for an animal to get in 90 seconds, no matter how you slice it.
