When Susan Wooten’s sighting in South Carolina began receiving more attention, one critic proclaimed that a large modern pterosaur would be impossible so near the Atlantic coast of the United States, for thousands of beach-goers would have seen it. That critics seems to assume that any large pterosaur living in South Carolina would have shown up at the beach in daylight, causing news headlines; since he did not see any relevant news report, then no large pterosaur could live there.
How rarely critics consider the whole picture! The overall reports of living pterosaurs around the world suggest these creatures are mostly nocturnal. It’s not just the rarity of daylight sightings. Specific flight behavior at night suggests they are nocturnal.
Then why should they ever appear in daylight? Consider two dramatic daylight sightings in Papua New Guinea, where the nocturnal ropen is believed to fly with a bioluminescent glow at night. Both cases involve a large or giant “prehistoric” creature, with no sign of feathers, flying at low altitude. Both may have been Rhamphorhynchoid pterosaurs, awakened from sleep in daylight and frightened into flying away from potential danger.
In 1971, in daylight, on Bougainville Island, Brian Hennessy saw something he will never forget. In his own words, “. . . our truck had stopped on our downward journey from the top of the range to the coast way below. . . . I can’t remember why our vehicle had stopped. Maybe we had to wait for another vehicle to pass us. . . . I saw a very unusual creature. Firstly, it was very big . . . a longish narrow tail . . .”
I asked Mr. Hennessy, “Was anything coming out the back of the head . . . a crest, appendage, horn, or comb?” He replied, “It was like a horn.”
The two vehicles may have startled the creature from sleep. Many years earlier and many miles to the west was another sighting.
In 1944, in daylight, west of Finnschafen (mainland New Guinea), Duane Hodgkinson saw something he will never forget. At the edge of a clearing, he and his army buddy were gazing at some large ants, bigger than any ants in Ohio. Some animal, at first unseen, came running through the grass. Something then flew up from the far side of the clearing, apparently startled by the running animal. Hodgkinson soon realized that it was not a bird, for it was too big and it had a long appendage coming out the back of the head. He then concluded that it was a “pterodactyl.” At about the time it flew away, a wild pig came running past.
I am convinced that both Hennessy and Hodgkinson saw Rhamphorhynchoid pterosaurs (on Umboi Island, the animal is called “ropen“). The 1944 sighting seems to have involved a large ropen awakened from sleep by a wild pig.
But the ropen is rarely seen in daylight, by Umboi natives. It is said to catch its food at night, on reefs that surround the island. Its described behavior resembles that of the kor, which islanders to the north say catches fish at night. Deep in the mainland of Papua New Guinea a large flying creature is said to fly at night: the indava. These three native names may refer to the same type of animal, for all accounts include a glow that flies at night. Of course intrinsic bioluminescence would not make it impossible for a creature to come out in daylight; it only makes a daylight appearance rare.
