...a rush of fossil discoveries has brought to light surprising new pterosaur shapes, sizes, and behaviors. Some paleontologists now suspect that hundreds of pterosaur species may have lived at any one time, dividing up habitats much as modern birds do. Their world included monsters like Quetzalcoatlus northropi, one of the largest flying animals yet discovered, nearly as tall as a giraffe, with a 35-foot wingspan and a likely penchant for picking off baby dinosaurs. But it also included pterosaurs the size of sparrows that flitted through primeval forests and may have fed on insects, large pterosaurs that stayed on the wing across oceans for days at a time like albatrosses, and pterosaurs that stood in briny shallows and filter fed like pink flamingos.
