Douglas Lawson found the first Quetzalcoatlus remains (that we know of; it is rather convenient that Mesoamerican mythology has a "feathered serpent god") and three years later rejected the idea of piscivorous diet. He, instead, opted for a scavenger's diet spotting carcasses from kills and natural death from the sky and gliding down to commandeer the animal from others in order to take a fairly easy meal. This, in turn, was rejected by Lehmann and Langston in 1996 who suggested that with a toothless beak and a certain configuration of the cervical vertebrae Quetzalcoatlus made for a competent skimmer. They proposed that the giant pterosaur flew over bodies of water at wave top heights picking out fish and anything else that wandered too close to the surface. A study in 2007 showed that drag and energy consumption in fighting drag would have been too large for the animal to sustain flight and get a worthwhile meal in this fashion however, and the idea was, again, rejected.
