MonsterQuest: Flying Monsters - History Channel (2009)

If there is one place on earth that could be home to a prehistoric flying monster, it is Papua New Guinea. These islands to the north of Australia are the closest thing to a real `lost world' and eyewitnesses here claim that a terrifying monster is circling above them.
Natives call this creature the `Demon Flyer', but its twenty-foot wingspan, gray leathery skin and crested head appear to be only one thing - a living pterosaurs.
Ancient sea charts made by early explorers in the sixteenth century show that they saw pterosaur-like animals and warned mariners of these legendary monsters. Palaeontologists, however, are doubtful and suggest that a more likely explanation is a yet to be discovered species of giant bat.
