She started a firestorm of controversy in and when she reported that she had sequenced proteins in the dinosaur bone.

Dinosaur Fossils Dated With Carbon | Live Pterosaur

Critics charged that the findings were mistaken or that what she called soft tissue was really biofilm produced by bacteria that had entered from outside the bone. Schweitzer answered the challenge by testing with antibodies. Her report in confirmed the presence of collagen and other proteins that bacteria do not make. In , a Swedish team found soft tissue and biomolecules in the bones of another creature from the time of the dinosaurs, a Mosasaur, which was a giant lizard that swam in shallow ocean waters.

Schweitzer herself wonders why these materials are preserved when all the models say they should be degraded. That is, if they really are over 65 million years old, as the conventional wisdom says. Dinosaur bones with Carbon dates in the range of 22, to 39, years before present, combined with the discovery of soft tissue in dinosaur bones, indicate that something is indeed wrong with the conventional wisdom about dinosaurs. However, it has been hard to reach the public with the information.

Despite being simple test results without any interpretation, they were blocked from presentation in conference proceedings by the North American Paleontological Convention, the American Geophysical Union in and , the Geological Society of America in and , and by the editors of various scientific journals. Fortunately, there is the internet. Carbon in dinosaur bones download more details.

Bow is the bulk organic fraction of whole bone; Col is collagen fraction; w or ext is charred, exterior or whole bone fragments; Hum is humic acids. Bioapatite is a major component of the mineralised part of bones. It incorporates a small amount of carbonate as a substitute for phosphate in the crystal lattice. Charred bone is the description given by lab personnel for blackened bone surfaces. Proteins that are the main component of connective tissue. Yet it is found in four-foot long, nine-inch diameter dinosaur femur bones claimed to be greater than 65 million years old.

The "Modified Longin Method" is the normal purification method for bone collagen. Libby, the discoverer of Radiocarbon dating and Nobel Prize winner, showed that purified collagen could not give erroneous ages. Click to see a You Tube video of the conference presentation.

This is what happens when you try to get members of the academic community involved: Click to see the YouTube video. Banned by the Center for Applied Isotope Studies. From through the Paleochronology group had 11 dinosaur bone samples carbon dated by the Center for Applied Isotope Studies at the University of Georgia, and for good reason.

Senior research scientist Alexander Cherkinsky specializes in the preparation of samples for Carbon testing. He directed the pretreatment and processing of the dinosaur bone samples with the Accelerator Mass Spectrometer, though he did not know the bones were from dinosaurs, and he signed the reports. Carbon dating at this facility is certainly the very best. But in , someone told the director of the facility, Jeff Speakman, that the Paleochronology group was showing the Carbon reports on a website and YouTube and drawing the obvious conclusions.

So when he received another bone sample from the Paleochronology group, he returned it to sender and sent an email saying: The scientists at CAIS and I are dismayed by the claims that you and your team have made with respect to the age of the Earth and the validity of biological evolution. Consequently, we are no longer able to provide radiocarbon services in support of your anti-scientific agenda. I have instructed the Radiocarbon Laboratory to return your recent samples to you and to not accept any future samples for analysis.

Notice that he did not say the radiocarbon reports of the dinosaur bone samples were inaccurate. No, his objection was that the Paleochronology group was using the reports as evidence that dinosaurs lived thousands, not millions, of years ago. So I asked him 3 times over 3 weeks what is the right conclusion to draw from the test results they provided us; then I asked his entire scientific staff.

None of them had an answer. This is an attitude we have encountered among members of academia: A nyone who challenges the established truth is made an enemy. The threat hangs over everyone. A manager of a commercial laboratory that does Carbon dating, Beta Analytic Inc. Her interest led us to propose that her company perform a Carbon test on a T-rex bone we acquired. Thanks for considering our service in this project. We wish you well in your research but must choose to opt-out of the analysis.

Since you have identified it as T-rex, and these are known to be extinct for 50 million years, it is beyond the limit of our dating. If a "recent" result was derived it would be universally challenged with possible risks of poor result claims for our laboratory. This is a project much better suited for collaboration with a university laboratory. It has demonstrated both the technical competency and management system requirements necessary to consistently deliver technically valid test results.

These standards are universally recognized as the highest level of quality attainable by a testing laboratory. Mark Armitage and the triceratops horn. Mark was suddenly terminated by the Biology Department when his discovery of soft tissues in a Triceratops horn was published in Acta Histochemica. The university claimed his appointment at had been temporary and claimed a lack of funding for the position. This was news to him, and contradicted prior statements and documents from the university.

Mark Armitage has a MS degree in biology and has been a microscope scientist microscopist for 30 years. He was the president of the Southern California Society for Microscopy for several years. He has some 30 publications to his credit. Mark's micrographs have appeared on the covers of eleven scientific journals, and he has many technical publications on microscopic phenomena in such journals as American Laboratory, Southern California Academy of Sciences Bulletin, Parasitology Research, Microscopy and Microanalysis, Microscopy Today and Acta Histochemica, among others. According to papers filed with the Superior Court of Los Angeles County, when Mark Armitage interviewed for an opening at CSUN for a "regular" "part-time" microscopist in he told the panel that he had published materials supportive of creationism.

William Krohmer, Manager of Technical Services and Safety, who would be Armitage's direct supervisor, was on the panel. The panel hired Armitage despite his creationist writings because of his exceptional qualifications.

The position was Electron Microscopy Technician in the Department of Biology, working two ten-hour days per week. He was "permanent part-time" and was allowed to enroll in the full benefits package of the university. He ran the Microscopy Imaging Facility with its three electron microscopes, personally training students and faculty on their proper use.

He was often praised for his work and accomplishments. The Biology Department bought a new confocal microscope that used high-powered lasers for imaging and was computer-driven. Armitage supervised the installation of the new microscope. He was assigned to be the only instructor on it, with responsibility for control and supervision of the instrument. In February , he was asked to teach a full graduate course in Biological Imaging for the Biology Department.

In March , Dr. Oppenheimer sent an email to staff saying that the two days per week that Armitage was working needed to be expanded in order to facilitate the growing demands of the microscopy lab. In June , Dr. Ernest Kwok was made chairman of the committee overseeing the microscopy lab, and became Armitage's new supervisor. In the summer of , Armitage responded to an invitation to participate in a search for dinosaur fossils in Glendive, Montana in the famous Hell Creek formation.

He found the brow-horn of a triceratops; it was not petrified. Studying the horn at the CSUN lab, he discovered soft tissue in the supposedly million-year-old or more fossil.

While teaching students how to use microscopes in the lab that he directed at CSUN, Armitage engaged them in brief socratic dialogue about the possible age of the horn. Kwok's students was stunned by the discovery and implications of soft tissue in the triceratops horn, and told Dr. On June 12, , Dr. Kwok stormed into Armitage's lab and shouted, "We are not going to tolerate your religion in this department! Armitage reported this to the Biology Department chair, Dr. They both played down the event and told Armitage to forget it. Praise for Armitage's work continued from distinguished members of the Biology Department.

In November , a photo of the soft tissue in the triceratops horn was published on the cover of American Laboratory magazine. The former chair of the Biology Department, Dr. Oppenheimer, wrote a ringing endorsement of Armitage in a letter of recommendation.

On February 12, , the journal Acta Histochemica published a paper by Armitage describing the discovery of soft tissue in the triceratops horn. Acta Histochemica is a peer-reviewed journal of structural biochemistry of cells and tissue that welcomes advanced microscopical imaging; it has been publishing since On the day the paper was published, Dr. Kwok called a secret meeting of the committee overseeing the microscopy lab. Armitage had served on the committee for three years, but he was not invited.

The committee decided to terminate Armitage. On February 19, , William Krohmer told Armitage that there was a "witch hunt" being mounted against him, and advised him to resign. When he refused to resign, Krohmer told him he would be terminated. Armitage was fired on February 27, He was told that his job had only been a "temporary appointment". There is a sidenote to this story. Hugh Miller, head of the Paleochronology group, obtained a bone sample from the triceratops horn Mark Armitage discovered. As you can see, the bone was dated by them to 33, years before present.

The data for their four dinosaurs is below. A remarkable find was published in the journal Nature in April The "bone bed is characterized by the presence of completely disarticulated skeletal elements at various stages of embryonic development". This made it possible to detect the preservation of organic residues, probably direct products of the decay of complex proteins , within both the fast-growing embryonic bone tissue and the margins of the vascular spaces. Our results clearly indicate the presence of both apatite and amide peaks within woven embryonic bone tissue, which should not be susceptible to microbial contamination or other post-mortem artefacts.

Embryology of Early Jurassic dinosaur from China with evidence of preserved organic remains. Radiocarbon RC or Carbon C dating of linen, cotton, bones, fossils, wood, sea shells, seeds, coal, diamond anything with carbon is one of the most common and well understood of the various scientific dating methods. Carbon is a radioactive isotope of carbon that is formed naturally in the atmosphere. All plants and animals have a regular intake of carbon while they are alive.

When an animal or plant dies, it no longer takes in carbon of any form. C has a half-life of years. The maximum theoretical detection limit is about , years, but radiocarbon dating is only reliable up to 55, years with the best equipment. Older dates are considered to be tentative. If, as generally believed, dinosaurs have been extinct for 65 million years, there should not be one atom of Carbon left in their bones. The accuracy of carbon dates depends on whether the ratio of Carbon to Carbon was the same in the past as it is today.

How Carbon Dating Works

There are two types of C dating technologies. The original one, counting Beta decay particles, is a multistep process and requires sample sizes of several grams. Beta counting is prone to possible errors in each of the many phases. AMS uses a much smaller sample size, and actually counts the Carbon atoms as they are separated from the sample. The equipment accelerates streams of charged atomic particles to high velocities in order to sort and analyze them. Carbon dating of bone is one of the most difficult tasks in carbon dating, and requires the most care of any carbonaceous material.

This is mainly due to the nature of bone, which is a very porous material. Certain parts of bone look like a sponge under the microscope. Many dinosaur bones are hard as rock because the original material has been replaced with a silicon material such as quartz. These are "mineralized" or "fossilized". We have found un-mineralized dinosaur bones. We then scrape the outer surface off to get rid of surface contamination, and date the inner remaining material. One can date just the purified bioapatite, the total organics, or the collagen, or a combination of these, as we did in several cases.

This is a remarkable find because collagen, being a soft tissue present in most animals, is supposed to decay in a few thousand years.

How Do Scientists Determine the Age of Dinosaur Bones?

Collagen is the main protein found in connective tissue of animals. It can make up from 1 to 6 percent of muscle mass. Triceratops and Hadrosaur femur bones in excellent condition were discovered in Glendive Montana, and our group received permission to saw them in half and collect samples for Carbon testing.

Notice the absence of report number five in the above image from the official conference web site. The Paleochronology group asked for an explanation; they were given the following:. No explanation is given by these two chairmen. Science, meaning real science, thrives in details. Raw censorship in this deletion of an abstract—that deserves an investigation. Typical error potential listed for the above C testing is only a few centuries but sometimes even less than one century.

Notice how greatly the above data vary from the millions-of-years figures commonly proclaimed in Western media and textbooks. Radiocarbon dating of dinosaur fossils has generally not been done until recent years, for the great majority of scientists had assumed such testing would be pointless.

Carbon should not exist in dinosaur bones, for it should have decayed away millions of years ago. But that idea comes from the assumption that those creatures actually lived millions of years ago, an assumption now challenged by other scientists. Those astonishing data give a clue why the research report was censored: It was revolutionary in a way that those two chairmen did not like. Dinosaurs have been carbon dated to much more recently.

Carbon Dating and Dinosaurs. Radiocarbon dating is the most accurate and most verifiable of the radiometric dating systems. Because so many paleontologists have so long assumed that all dinosaurs became extinct many million years old, the abstract of the report by the Paleochronology group was censured, deleted from the conference website because they did not like to consider such an apparently revolutionary discovery.

Decide for yourself if this is a case of censorship. Radiocarbon Dating of Dinosaur Fossils. Carbon dating was recently performed on dinosaur fossils,1 and the results were presented at the Western Geophysics Meeting in Singapore, August , a gathering of approximately two thousand scientists.
