Results of Investigations Concerning Pterosaur Sightings In Papua New Guinea

Spatial Scaling Procedure

(Excerpts of original report are on the left; explanations by Whitcomb are on the right.)

Tree Trunk Diameter: .9144 m  (assumed)

Pixels Across Trunk: 8 pix;

then 8 pix/.9144m = 8.7489 pixel/meter and

Source 1: (8 pix)/(8.7489pix/m) = 0.914 m

Source 2: (10 pix)/(8.7489pix/m) = 1.143 m


These are the scaling values used in this investigation.

The above still image, taken from the daylight video by Paul Nation, shows where the two “ropen-lights” were videotaped the previous night (although the creature is called “indava” in this area of Papua New Guinea). At the top of the “saddle,” is where the two creatures were reported to have been glowing when the earlier video footage was obtained. Paiva magnified the still image and estimated the size of the tree; this estimate was used in calculating the size of the lights in the other video footage, for the camera was in about the same place during both videotaping sessions.


The point is that each of the two lights is about one meter in diameter, the lower-left light being slightly less than, and the upper-right light being slightly more than one meter across (flat-measurement). Whatever these two lights were, they were obviously not fireflies.

In addition to Papua New Guinea, sightings of apparent pterosaurs have been reported in Europe (“Ropens . . . ‘dragons’ were not all killed by knights.”) and in Australia (Perth and Eastern).
