text: Over the past hundred years or so, there have been more than a dozen expeditions into the deep jungles of the Congo basin in search of an allegedly dinosaur-like creature called Mokele Mbembe.\n\nRedmond O'Hanlon's account of his failed expedition (Congo Journey, 1996) makes for excellent reading, even though they didn't find anything.\n\nThe 1992 British expedition with William Gibbons has one photograph that in rather unusual, and it is claimed that it may be the head of a Mokele Mbembe.\n\nA 1987 Japanese expedition has some amazingly awful, blurry video footage that they claim is one of the beasts moving slowly through the water, but most of those who have seen it says it looks more like a boat with two people in it, one of whom is standing up.\n\nA 1980 American expedition has some castings of what may be footprints, that appear to be round with three sharp claws on them.  There's no known critter that leaves prints like that.\n\nThere have also been numerous 'sightings' of giant flying reptiles around the world.  It has been spotted in tropical Africa, the US Southwest, Mexico, the Andean highlands of South America and tropical New Guinea.  Dubbed Kangamato by cryptozoologists, some have tried to claim they are surviving remnants of pterosaurs, but there is little to no hard evidence for their existence, and they may well be Byakhee instead.\n\nOther than Nessie, Champie, Ogopogo and other lake critters that have varying degrees of evidence for their existence, those are about the best documented sightings of prehistoric-type reptiles.
