Scientific Paper on Radiocarbon in Dinosaur Fossils

The most recent issue of a scientific journal (Creation Research Society Quarterly) including the article “Radiocarbon in Dinosaur and Other Fossils.” The following are excerpts from that scientific paper.


The consistent failure of carbon dating facilities to find carbon-dead samples . . . highlights the regularity with which they have detected measurable amounts of radiocarbon in samples from Phanerozoic settings. . . .

Comparing Laboratories

We considered the possibility that error could arise from a given carbon-dating facility, for example by operator error on a given day.

Our 16 results from a carbon isotope facility that specializes in bone tissue combine with similar detections of radiocarbon in Phanerozoic fossils from GeoChron Laboratories in Massachusetts, the IsoTrace Radiocarbon Laboratory at the University of Toronto in Ontario, the Australia Nuclear Science and Technology Organisation (ANSTO), and the Jena AMS system at the Max-Planck Institut Fur Biogeochemie.

The most parsimonious explanation for five different laboratories detecting radiocarbon in ancient fossils seems to be that these fossils contain endogenous 14C.


On the basis of repeated observations of original tissues found in dinosaur and other bones, and on the basis of prior researcher’s difficulties in finding a reliable source of carbon-dead earth material to calibrate highly sensitive AMS systems, we tested 16 fossil samples for the presence of 14C. Our fossils came from seven dinosaurs . . .

We sought to falsify the hypothesis that this radiocarbon originated from our fossil material first by comparing our amounts of measured radiocarbon to those already published, finding general concordance between our data and already published data. Second, all samples regardless of geographic and even stratigraphic provenance, showed detectable 14C within a total age range spanning orders of magnitude smaller than the conventional age range for these fossils.

A Translation into Simple English (for non-scientists)

A number of laboratories came up with the same results for dinosaur fossils: Those bones were not nearly as old as many scientists have long assumed. They are tens of thousands of years old, not millions of years old. In other words, dinosaurs have lived in human times.



Dating Dinosaurs With Carbon-14

The [radiocarbon] technique of dating fossils is an established way to determine the ages of archaeological specimens, sometimes accurate from 500 to 50,000 years old . . . It has often been used by scientists . . .

Radiometric Dating Censored (Recent Dinosaurs)

It was two chairmen of the Western Pacific Geophysics Meeting in Singapore, a five-day conference held in August of 2012. They apparently gave no objection, during the conference, to any of the materials presented by the Paleochronology group.

Dinosaur Bones – Radiocarbon Dating

Dinosaur bones . . . are younger than anyone ever guessed.  Carbon-14 (C-14) dating of multiple samples of bone from eight dinosaurs found in Texas, Alaska, Colorado, and Montana revealed that they are only 22,000 to 39,000 years old.

Scientific Dating of Young Dinosaurs

A number of pieces of dinosaur bones found in North American have been dated in recent years. So how many millions of years old are those fossils? Well, they’re not actually that old, apparently, dated at tens of thousands of years old, according to carbon-14 testing.

Ropen-Pterodactyl in Utah and Arizona?

Note that the phrase “flying dinosaur” is technically inaccurate, for pterosaurs are not actually dinosaurs. Some persons call them “prehistoric birds” or “pterodactyls,” although that’s also incorrect terminology. The ropen is considered, by some cryptozoologists, to be a modern Rhamphorhynchoid pterosaur.

Three things set the featherless ropens apart from bats:

  1. Long tails (Finschhafen-1944 sighting estimate: 10-15+ feet long)
  2. Size (many estimates with wingspans over ten feet)
  3. Bioluminescent glow

An Apparent Large Glowing Ropen in Utah

My wife and I visited Devon and his brother Dallin in St. George, Utah, this past Thursday, and they told us about the extraordinary encounter they had in Grantsville, Utah, fourteen years ago. These two young men were two of the three boys who witnessed the glowing creature just south of the Great Salt Lake.

It was between 10 p.m. and midnight when they saw the glowing bird-like thing flying overhead. The nearby farm animals went wild with noises farm animals make when they are terrified. The three boys (aged 12-14) were also excited, bewildered at what they were seeing.

Both Devon and Dallin described the huge flying creature as glowing, although the glow would turn off and on. Devon estimated the wingspan was about twenty feet, although he said it could have been fifteen feet.

An Apparent Pterosaur in Arizona, in Daylight

In 2011, a man reported to me that four years earlier he had seen a strange flying creature in Phoenix, Arizona. Here is part of his report:

I was outside . . . looking over at the salt river bed [near] the airport when I saw a very large ptero something swoop (glide) in and land . . . [It] was spashing in the water. It had no feathers and it was very large! It had what looked like really old worn out leather wings and a thing coming out of the back of its head.

Possible Baby Pterosaur in Arizona

The following is part of what was reported to me in November of 2012:

To whom it may concern, I have seen one of these creatures under a bridge near Tucson Az. It was a baby and was covered in soft whitish looking fur or down. The top of its head was moulting [sic] with a top knot protruding. . . . We were standing not more than 15 ft from this “baby.” It was unhappy with our arrival and spread its wings out and tried to adopt a threatening birdlike attack but it was almost toppling over onto its face because of the incredible wingspan  measuring at least 3 to 4 ft on each side . . .

Taking the Utah and Arizona Sightings in Context

If those few sightings in Utah and Arizona were the only reports of modern long-tailed pterosaurs in North America, they would indeed give little support to the idea that such flying creatures are still living. Yet they are only a tiny portion of the sightings of apparent pterosaurs in this part of the world, encounters with both obvious pterosaurs in daylight and huge glowing flying creatures at night.



Bioluminescent Ropen of Papua New Guinea

American cryptozoology author Jonathan Whitcomb believes the ropen of Umboi is related to the “Gitmo Pterosaur” of Cuba.  . . . A lady describes how the glowing ropen flew over Lab Lab Village (Umboi Island, PNG), one night.

Dinosaurs Living With Humans

Dr. Dennis Swift has spoken much and written much about the concept that people, in earlier centuries, have lived with dinosaurs. The following is just a brief summary of what he has revealed about evidences that ancient people have lived with extant dinosaurs.

Flying Creature Called “Ropen”

What do we know about the ropen? It is not confined to Papua New Guinea, which makes sense when we consider that the largest ones have wingspans greater than twenty feet. Flying creatures similar to the ropen of the southwest Pacific have been reported in Asia, Europe, Africa, and North America.

Ropen From the Jungles of Papua New Guinea

It is described as a large, featherless flying creature with a long tail. It is reported to glow at night, in a way suggesting the animal controls the light (called “intrinsic bioluminescence”).

Flying Fox Bat or the Ropen

Why are fruit bats not what was observed? Eyewitnesses do not describe creatures with no tails and  with wingspans of seven feet; they observe creatures with tails longer than seven feet and wingspans  greater than twenty feet.

Ropen of North America

For generations, Americans have known the phrase “life, liberty and the pursuit of happiness.” It’s in the Declaration of Independence. Yet how important is knowledge in preserving human life! When it comes to keeping themselves alive, people have the right to know the truth.

Dating Dinosaurs With Carbon-14

Introduction to C-14 Dating

The carbon-14 (14C) method of dating biological material was developed by the American physicist Willard Libby in the mid-20th century. He was awarded the Nobel Prize in Chemistry for that achievement. This scientific method for determining ages of specimens is also called radiocarbon dating, abbreviated RC.

The 14C technique of dating fossils is an established way to determine the ages of archaeological specimens, sometimes accurate from 500 to 50,000 years old, although adjustments may need to be made for oceanic organisms that are tested. It has often been used by scientists such as geologists (Pleistocene materials), anthropologists, archaeologists, and other scientific investigators.

Until recent years, however, it was rarely used with any dinosaur bones, for most Western scientists had long assumed that all dinosaurs and pterosaurs had become extinct many millions of years ago. If the old assumptions were correct, it would seem pointless to try to date a fossil of such a creature by the radiocarbon process, for no 14C would be expected to still exist in it.

Yet scientific progress sometimes involves astonishing new discoveries and concepts, and the previously-assumed ages of “prehistoric” fossils is now being disputed.

Take Recent Scientific Testing in Context

When ordinary persons, who are not scientists, read a little about scientific testing that indicates dinosaurs may not be so old, it may leave an impression. But when an ordinary person sees an apparent pterosaur flying overhead, the impression is overwhelming.

From the book Searching for Ropens and Finding God (4th edition, nonfiction, page 309):

Data from the 128 sighting reports demonstrates no significant number of hoaxes could have been involved. Examining a few of the critical sightings shows how unlikely misidentifications could have been involved. That can open our minds to the possibility that most of those 128 reports are more likely than not to have come from encounters with modern pterosaurs. That is when simple math takes over, making it practically impossible for all of those reports to have come only from non-pterosaurs. Remember: only one modern pterosaur disproves universal extinction.

The Paleochronology Group

From their web site on radiocarbon dating:

Almost all paleontologists never date dinosaur bones, because they have assumed for some time that the bones have to be millions of years old. True science is all about measurements and verifications of the assumptions underlying each old theory in order to improve or replace outdated ideas. Scientific methods and instrumentation have greatly improved since the earlier days of dinosaur dating, and those old assumptions are now being tested.

What Dinosaurs Were Involved?

Bones of an Acrocanthosaurus were 14C dated as recently as 23,760 years (+/- 270 years) before the present (excavated in Texas). An Allosaurus excavated in Colorado was 14C dated 31,360 years before present (+/- 100 years). A Triceratops found in Montana was dated as recently as 24,340 years before present (+/- 70 years).

A Simple Explanation

Why does 14C dating continue to give results that are so shocking? Dinosaurs living only tens of thousands of years ago—that shocks many persons. Yet the simplest explanation is this: Those dinosaurs whose bones were tested with the trusted radiocarbon method lived much more recently than the old assumptions had proclaimed.



C-14 Dating of Dinosaur Bones

Some scientists believe that dinosaurs lived much more recently. In fact, some researchers believe that dinosaurs and pterosaurs lived in human times, the source of some legends of dragons.

“Since the 1800’s, dinosaur bones have been assigned ages according to their place in the geologic column.” [This need a major revision, since they have recently been dated to much more recently.]

Smithsonian Runs Away From Discovery

Switek had best stop ridiculing those with different religious beliefs from his own and start looking at the important eyewitness testimonies that he ignored in his Smithsonian Magazine blog post.


Dinosaurs Living With Humans

Dr. Dennis Swift has spoken much and written much about the concept that people, in earlier centuries, have lived with dinosaurs. The following is just a brief summary of what he has revealed about evidences that ancient people have lived with extant dinosaurs.

Acambaro Figurines

Waldemar Julsrud, a German living in Acambaro, Mexico, discovered some unusual objects while riding his horse around El Toro Mountain, in July of 1944, including a partially buried ceramic figurine. This led, in time, to the discovery of many more ceramic works of art, some of which depict dinosaurs.

According to Dr. Dennis Swift, who in recent decades has specialized in these discoveries of ancient artifacts, thousands of these works of art were excavated, turning Julsrud’s mansion into “the museum that seared scientists.” It was not just the figurines of dinosaurs; various races of people were displayed on the clay: Eskimos, Asians, Africans, Caucasians, Mongols, and Polynesians. Over 37,000 works of art were uncovered in this part of Mexico alone, beginning in 1944.

Lack of any significant modern fraud

Contrary to what some skeptics proclaim, the vast majority of figurines from Acambaro are truly of ancient date, with much testing that has confirmed their antiquity. Those few recent imitations show far different characteristics in a variety of ways, making those exceptions irrelevant.

If persons in the mid-twentieth century were responsible for all of the dinosaur artwork that looks ancient, why do those depictions show dinosaur features that were not known to modern paleontologists until the late twentieth century? Why do these apparently ancient artistic depictions of dinosaurs show us the way their tails were held up according to recent discoveries? It’s because those works of art are indeed ancient and created by human artists who lived at a time when dinosaurs were known to them, centuries ago.

(In 1968, when Dennis Swift was still in high school, he heard about the Acambaro discoveries. That was about the time when a few forgeries were made in imitation of the originals, when Dennis and I were teenagers, so even those few forgeries are now ancient—humor intended.)

Wikipedia Errors

If you search on Wikipedia (at least until early January 20, 2015) with “Acambaro figurines” the system will automatically redirect you to the page “Acambaro figures.”

Early on January 20, 2015, I looked at the Wikipedia page for “Acámbaro figures” and found 24 uses of the word figure. The proper word for these works of art is figurines. Only eight times is the proper word used on that Wikipedia page. Above the “see also” and references sections of the page, almost every paragraph has this inappropriate word usage: figure. (The reference section itself does not have that word.)

That kind of error is not in itself evidence that the person (or persons) who wrote that Wikipedia page is mistaken about the credibility of these many thousands of ceramic works of art. But if the writer was careful about facts in the historical points, why does it say there “are several thousand” of those figurines when one of the leading experts in the world, Dr. Dennis Swift, says over 37,000 were discovered?



Dinosaurs of Acambaro Figurines

Julsrud at age sixty-nine was on the brink of making a discovery that may prove to be the greatest archaeological discovery ever made. Waldemar hired a Mexican farmer, Odilon Tinajero, to dig in the area where the ceramic figurines were found and bring him any other similar objects. Soon Tinajero had a wheelbarrow full of ceramic pottery that had been excavated on El Toro Mountain.

Nonfiction book on Acambaro figurines

“Hapgood researched the Acambaro collection . . . with Erle Stanley Gardner . . . in the mid-1960s. . . . hundreds of clay figurines that are apparently thousands of years old; however, they depict such bizarre animals [dinosaurs] and scenes that most archaeologists dismiss them as an elaborate hoax.” . . . [but] the evidences for authenticity were not considered [because of bias against the possibility of modern pterosaurs living alongside humans].
