Great painting of the biggest flyer of all time

Calling it "Big Bird Goes Postal," the fellow who styles himself "The Optimisitc Painter" has produced a great concept of the biggest flying creature ever. He writes, "Quetzalcoatlus is a Pterosaur, and so far as we know, the largest animal known to have flown. Once you start imagining something as tall as a giraffe with the wing span of a Cessna flying about it begins to boggle the mind." He based it on Dr. Darren Naish's paper with Mark Witton that argued pterosaurs did not swoop down and snatch up prey but walked most of the time like colossal land-based storks.
