My problem with the higher end estimates of mass is that the power requirements are rather ridiculous -- because higher weight increases ideal and stall speed, power requirements for flight scale as the 3/2 power of body weight and wind up in the 3 kW range for 250 kg flier with a 11m wingspan.
Well, what kind of ST do you estimate would be enough?

And what kind of flight would you imagine for a pterosaur of 500+ lbs.?

If they eat fish, they need to be able to pluck the fish from where they find them. I guess pterosaurs of this size are unlikely to be able to almost hover as they feed, like seagulls seem to do. Albatrosses? Or like no bird, given how the wings are apparently very different.

What kind of Move is their standard 'cruising' speed, what's their stall speed and what's a plausible maximum Move?
