More Pterosaurs in Utah

Rhamphorhynchoid pterosaur sketch

On August 13, 2015, I received an email from an eyewitness living South of Provo, Utah. It confirms earlier reports of apparent pterosaurs in Utah, especially nocturnal flying creatures that are very large. Here is part of what the new eyewitness reported to me: Well, last night I was outside in my backyard in Spanish Fork, UT, we […]

Pennsylvania Pterosaurs

forested area around the Susqauehanna River in PA

Does a species of ropen live in Pennsylvania or at least pass through that state on occasion? We need to keep these sighting reports in context, for other eyewitnesses have seen similar featherless flying creatures in surrounding states of the USA, including Ohio and Virginia. We also need to keep in mind the concept that […]

Possible bioluminesce in a flying predator?

I have no clear estimate for the probability that strange lights in deer camera photos, from the state of Mississippi, are from bioluminescent ropens, to the best of my knowledge as of early January 22, 2015. The honesty-credibility of the couple who own the property in Jackson County, Mississippi, however, demands that I present to you what […]

Ropen Lights in Southern California?

train bridge in a desert in California

Ghost Lights of Anza Borrego State Park—that video appears to be no longer available online except for the first few minutes of the documentary, which introduction enlightens us on how the mysterious flying lights terrified railway workers in the nineteenth century, in a desert in Southern California. The video calls the flying lights “a large number of unexplained floating […]

Comparing Interpretations of Marfa Lights

front cover of a nonfiction book by James Bunnell

We have an interesting selection here, for interpretations of Marfa Lights in Texas. Take your pick: Ordinary car headlights Extraordinary flying dinosaurs Dancing ghosts Effects of solar activity Plasma related to geology To narrow down the range, let’s get rid of something right away. No, not the flying dinosaurs, for the actual theory is more involved […]

Scientists and Live Pterosaurs

Posted on
tree-lined Yakima River in rural Washington state

What do scientists think about pterosaur sighting reports? Many of them have probably never heard about any relevant research. We need to remember that searching for live “pterodactyls” is still within the realm of cryptozoology, for we don’t yet have any living or recently-deceased animal to examine. For now, let’s see what one biology professor has done […]

Manta Rays or Modern Pterosaurs?

Sordes Pilosus Rhamphorhynchoid pterosaur silhouette

Introduction A recent post by Dale Drinnon brought up an old suggestion that sightings of giant long-tailed pterosaurs may be misidentifications of large Manta rays (a type of fish) that leap out of the sea. Let’s examine this idea in more detail than is seen in Drinnon’s brief commentary. First we consider the limitations of his […]

Bioluminescence in Pennsylvania: A Strange Flying Creature Glowing A few weeks ago, I received an email from a lady who was a passenger in a car one night; both driver and passenger saw a glowing creature as the strange thing flew by. Afterwards she did some research and told me, “I have found that a pterosaur is identical to what […]

Bioluminescent Barn Owls

Posted on

The other day I received a package from Australia, from Fred Silcock, who is probably the world’s leading expert on intrinsic bioluminescence in Barn Owls. One item in the package was a copy of an article from BBC Wildlife. But how do barn owls relate to reports of a live pterosaur? It’s the bioluminescence, or […]

Pterosaur Bioluminescence and “Red Herrings”

Posted on

Recently, a cryptozoologist critical to the possibility of a live pterosaur dismissed all potential sightings of bioluminescent pterosaurs as marsh gas or “spook lights.” He referred to all potential sightings of bioluminescent pterosaurs as “red herrings.” It was actually only a brief aside on a blog post titled “Ropens, Pterosaurian Sightings And Manta Rays,” but that critic seems […]

Bioluminescence of Pterosaurs

Posted on

How do we know that modern pterosaurs, at least some of them, are bioluminescent? Some eyewitnesses see glowing “pterodactyls” or a large or giant flying object that shines where large or giant pterosaurs have been seen to fly. No biology textbook explains anything about pterosaur bioluminescence, at least not yet; but my associates and I believe […]

Woetzel ropen sighting of 2004

David Woetzel, American cryptozoologist and explorer

“Ropen” is what natives of Umboi Island call the nocturnal flying creature, and legends abound. Most eyewitnesses have only seen it from a distance, at night, and they describe a strange flying light. David Woetzel led the second ropen expedition on Umboi Island, Papua New Guinea, late in 2004, accompanied by fellow-American cryptozoologist Garth Guessman. […]
