It is our conjecture that the pterosaur spends a lot of time in water. Here again we have one close to water and with apparently leathery wings. Assuming that its head and neck is tucked back as some birds do, we produce these observations easily enough.
Its flying ability is definitely odd and needs reflection. On a glide path appears our best choice now, except what is described is plausibly too nimble.
We have now received a fair number of credible pterosaurs sightings and we can sense some shape to it all. I suspect that this creature is nocturnal and seriously aquatic. It hides out in deep water during daylight and then uses its flying ability at night to search for another fishing hole. The creature is large and uses a large range making sightings seriously rare.
