From the nonfiction cryptozoology book Modern Pterosaurs:
Title page [in part]: Modern Pterosaurs - Human encounters with living "pterodactyls"
On January 14, 2017, Clifford Paiva and I spoke by phone and agreed that a photograph we had been studying had a genuine image of a real animal. We did not insist that this must have been a species of Pteranodon killed during the American Civil War. . . . . .
This [book] is an evaluation of the photograph we call Ptp, along with reports of human encounters with similar flying creatures around the world. Jonathan David Whitcomb
. . . How could a photograph of a modern pterosaur have gone unappreciated for a century and a half, plainly visible yet mostly ignored by Western scientists or unknown to them? You'll get explanations here [in this book]. . . . . .
Once you know what's been flying overhead, what people around the world have been encountering, you'll be better prepared to see and understand the details in Ptp. You should then appreciate what has always been available to those with eyes to see. . . .
Chapter 1: Where's the photo?
. . . In the summer of 2004, I got an email from the World War II veteran [Duane Hodgkinson], which included this:
On this one particular trip we had the wonderful opportunity to witness a pterodactyl take off from the ground and then circle back overhead and to the side, giving us a perfect side view which clearly showed the long beak and appendage protruding from the back of its head . . . [sighting in New Guinea, 1944]
He told me that the wingspan was about that of a Piper Tri-Pacer (about 29 feet). . . . After the creature had circled back, again coming into view of the two soldiers, it flew out of their sight again. Only then did the two men remember that they had a camera.
. . . I still find eyewitnesses who, like Hodgkinson and his buddy, don't even think of looking for a camera until the apparent pterosaur has flown away. Some of the eyewitnesses try to come up with a non-pterosaur explanation until the animal is gone, racking their brains to understand what they see until it has flown away: too late to search for a camera. . . . . .
Chapter 7: Photo of a pterosaur
I don't know when I first saw the photo that we now call Ptp. It could have been around 1968, in the main branch of the public library in Pasadena, California. I know that some persons believe they saw it in a book . . . around the 1950's to the 1970's.
I got an email from a Tom Payne, early in 2017, and he told me he remembers this photo from a book he saw when he was in his twenties, which would put his encounter, with the photo, in the 1970's. Here's part of what he told me:
I've canoed all my life. I've owned several of them. Those [wings of the animal in Ptp] aren't halves of a canoe! . . . Too narrow, too shallow. And definitely not a dugout canoe! Check out the uniforms! The guy on the right . . . has a left handed holster . . . I have a degree in computer science. I can tell you that technology [Photoshop] wasn't available to modify a photo like this before about 1980. . . . I've always been convinced that this is an authentic photo . . . Thanks.
