Africa's Kongamato

Was this a UFO - I doubt it but was it a dinasaur either? Where did it ccome from?

Reports of pterosaur-like creatures have come out of central Africa While traveling though Zambia in 1923, Frank H. Melland collected reports from natives of an aggressive flying reptile they called kongamoto, which means "overwhelmer of boats." The natives, who were occasionally tormented by these creatures, described them as being featherless with smooth skin, having a beak full of teeth and a wingspan of between four and seven feet. When shown illustrations of pterosaurs, Melland reported, "every native present immediately and unhesitatingly picked out and identified it as a kongamato."
In 1925, a native man was allegedly attacked by a creature that he identified as a pterosaur. This occurred near a swamp in Rhodesia (now Zambia) where the man suffered a large wound in his chest that he said was caused by the monster's long beak.
In the late 1980s, noted cryptozoologist Roy Mackal led an expedition into Namibia from which he had heard reports of a prehistoric-looking creature with a wingspan of up to 30 feet.
