Lake Pung-Seven boys, in 1994, saw the giant ropen flying over this crater lake. An American forensic videographer, in 2004, interviewed three of the young men: The ropen has no feathers; its wingspan is at least seven meters; the mouth is "like a crocodile;" its long tail has a "diamond." An Australian couple and a U.S. World War II veteran also describe this giant "pterodactyl" of the Southwest Pacific islands. This investigation by a legal videographer penetrates to the heart of the case: Standard models of biology are at fault. Eyewitness testimonies have been examined and alternate explanations, scrutinized. The result? The ropen is a Rhamphorhynchoid pterosaur.
