Pterodaustro guinazui

About 100 million years ago, a flying reptile called Pterodaustro guinazui soared above the coast of what is now Argentina. With its 8-foot wingspan, Pterodaustro was nearly the size of a condor. But when it came to feeding, this pterosaur was probably more like a flamingo than a bird of prey. Pterodaustro probably waded near the shore and scooped up water and strained it for food through fine, bristle-like teeth.
