Re: Pterosaur in water Re: Fw: Water-bourne pterosaur launch

There is indeed a possibility that many pterosaurs, even pelagic ones, could barely swim. However, their anatomy suggests that they could, unlike a Frigate Bird, take off from the water if they were unlucky enough to end up in it for any number of stochastic reasons. Frigate birds have very unusual limb morphology among birds; this would appear to be why they cannot launch from water.

Ok, it just occurred to me I've not seen a representation of a pterosaur
in water. Did a quick google search but nothing yet.

So, did they sit in the water like a duck? How were the wings folded? etc

Is there a pic someone's done? Having troubles visualizing this water
take off...

There's every possibility that they couldn't swim at all. Frigate birds spend their entire lives around the ocean, but if they land in the water they risk drowning. Holiday resort operators in Queensland often have to rescue frigate birds from their fresh-water beach-side pools, which the birds skim for
a drink.
