Pterosauria

(Obviously the best Mesozoic winged vertebrates.)

Nyctosaurus sebulbai by Jaime A. Headden:

No, this isn’t a real animal.Nyctosaurids are pterosaurs with incredibly long arms, but comparatively short feet. Darren Naish once speculated ([link]) that pterosaurs could attain flightless status in much the same ways as birds do, with reduction of the forelimbs and wing form, developing elongated hindlimbs in azhdarchid-like taxa and thus become giraffe or horse-like “quadrupedasaurs.” I wonder if the selection on the wings for form are so intensive this could ever happen. Indeed, it seems that it would be the feet first to go, the wings second, if ever. What if, instead, we got pterosaurs who walked with their wings, freeing their feet from locomotion?

There’s a bit of a story behind the source of this picture, the gist of it is that this was supposed to be the first panel of a short comic that I may or may not finish. At least it makes a nice stand alone picture, right?
(Also, this is my first proper, fully coloured digital piece, yaldi!)
