I’m grateful to this new subscriber, from the UK, who has been active in cryptozoological research (he recently gave me important information on another unrelated sighting report). By the way, Namibia, on the southwest coast of Africa (much desert), is the second most sparsely populated country in the world, according to Wikipedia.
A desert is not usually the best place to search for a living pterosaur, but a few eyewitness accounts are of such sightings. Consider one sighting in a Southern California desert. The eyewitnesses estimated that the flying creature may have been three times the size of an eagle.
The late-ninteenth century Tombstone newspaper account has limited credibility. Why? For one thing, that was a period in Western American history when some newspapers are said to have fabricated stories when things became quiet. A giant pterodactyl in the desert may have been one of those fabricated stories. Nevertheless, if anyone has any historical information that might verify that account, please let me know by email. Thank you.
