The Kongamato, according to Wikipedia, is said to reside in Western Zambia, Angola and Congo (Africa). According to In Witchbound Africa (non-fiction book by F. Melland), this very dangerous creature flies along certain rivers, attacking small boats, at times, hence the name that means “breaker of boats.” Although the wingspan seems smaller than the ropen of Papua New Guinea (four to seven feet), some pterosaur-like creatures in P.N.G. have been described as about that size, especially the kor of the Manus Island area (northern P.N.G.).
But what about the “flying snake” of Namibia? According to research done by the British cryptozoologist Richard Muirhead, one of these creatures “swooped down” from a cave near Kirris West, in 1942, (sixty miles east of Keetmanshoop, south-west Namibia.) It left a trace of something on the ground and a burning smell. Could that burning smell be related to the cause of death of a fisherman who was killed by a kor (northern Papua New Guinea, 1960’s)? The man died three days after being attacked by the pterosaur-like animal; his body was not just torn: It was also burned. In at least one other area of Papua New Guinea, the creatures are said to drip a liquid that can burn human skin.
