In order for C14 production in the dating to c14 constant, cosmic ray influence, which creates C14, method be consistent. So they remain success stories, innocent until proven guilty.

I posted comments that he at first answered and then removed when he saw they demolished his position. Here are just a handful of known situations where radiocarbon dated incorrectly. Feb 18,  · Radiocarbon dating is a popular dating method the general public is fairly familiar with. Though they may know it as carbon dating or carbon 14 dating. The Dating Game by Rick Groleau So what's the story behind radiocarbon dating?

It's not a love story, to be sure. Rather, it's a way to determine the age of organic. The stronger the field is around the earth, the fewer the number of cosmic rays that are able to reach the atmosphere. Radiocarbon dating is a radiometric dating method that uses (14 C) to determine the age of carbonaceous materials up to about 60, years old. The technique was. The age of the Neapolitan Yellow Tuff caldera-forming eruption (Campi Flegrei caldera – Italy) assessed by 40 Ar/ 39 Ar dating method. Are tree-ring chronologies reliable?

Carbon dating dinosaur bones

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. 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.

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.

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.

On June 12, , Dr. Armitage reported this to the Biology Department chair, Dr. They both played down the event and told Armitage to forget it. 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. 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. 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. Both bones were tested by a licensed lab for presence of collagen. Both bones did in fact contain some collagen. The best process Accelerator Mass Spectrometry was used to date them. Total organic carbon and dinosaur bioapatite was extracted and pretreated to remove potential contaminants, and concordant radiocarbon dates were obtained.

They were similar to radiocarbon dates for ice-age megafauna such as Siberian mammoths, saber tooth tigers of the Los Angeles LaBrea Tarpits, sloth dung, and giant bison. We usually prefer AMS dating because of its inherent superior accuracy, but use the conventional method when large samples are available in order to completely rule out contamination. This is recommended by a carbon-dating laboratory specialist.

Robert Bennett, physicist and co-author, agree that "the AOGS-AGU assembly encourages presentation of reliable data even though the topic may be controversial. This is a very wise policy for the advacement of science and the education of people everywhere. Thus, we encourage our colleagues to do their own carbon dating of dinosaur bones from museums and university fossil repositories around the world, as well as testing for C in scrapings from dinosaur bones as they are excavated.

We are anxious to see their results presented, just as we have done. Also, we call on the news media and citizens everywhere to urge paleontologists, curators, university faculty, and government scientific agencies to encourage and support further testing for C content in dinosaur remains. Scientists need to know the actual chronology of the Earth and the age of the fossils. Download pdf of data and commentary. More censorship by "scientists".

Waldemar Julsrud, a German hardware merchant in Acambaro, Mexico, was riding his horse on the lower slope of El Toro Mountain on a sunny morning in July Suddenly he spotted some partially exposed hewn stones and a ceramic object half buried in the dirt.

He dismounted and dug out of the ground the hewn stones as well as a few ceramic pieces. Julsrud, who was archaeologically astute, immediately realized that these ceramic pieces were unlike anything that he had seen. The objects he held in his hand were distinctively different than any other known Indian culture.

When a few ceramic fragments were found there, Julsrud hired diggers to excavate. This discovery brought world wide attention from archaeologists who at first mistakenly defined them as Tarascan, but later they were correctly identified as a whole New Indian culture - the Chupicuaro.

Julsrud at age sixty-nine was on the brink of making a discovery that may prove to be the greatest archaeological discovery ever made. He 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. Charles Hapgood notes that "Julsrud was a shrewd businessman and he now made a deal with Tinajero that is very important for our story.

He told Tinajero that he would pay him one peso worth about 12 cents for each complete piece he brought in. The objects were made of clay and stone, varying in size from a few inches long to statues three feet high, and dinosaur objects four to five feet long. In the collection, that now numbered over 20, objects, not one could be found to be a duplicate of another.

Each of the clay pieces had been individually made, without molds, skillfully sculptured, and carefully decorated. Several hundred of the figurines were scientifically identified as representing many species of dinosaurs, including duck billed Trachodon, Gorgosaurus, horned Monoclonius, Ornitholestes, Titanosaurus, Triceratops, Stegosaurus Paleococincus, Diplodocus, Podokosaurus, Struthiomimos, Plesiosaur, Maiasaura, Rhamphorynchus, Iguanodon, Brachiosaurus, Pteranodon, Dimetrodon, Ichtyornis, Tyrannosaurus Rex, Rhynococephalia and other unknown or as yet unidentified dinosaur species.

These remarkable dinosaur figurines threaten orthodox concepts and time scales in many fields of study. Sanderson was amazed in to find that there was an accurate representation of the American dinosaur Brachiosaurus, which was almost totally unknown to the general public at that time. Sanderson wrote about the figurine in the Julsrud collection. It is about a foot tall. The point is it is an absolutely perfect representation of Brachiosaurus, known only from East Africa and North America.

There are a number of outlines of the skeletons in the standard literature but only one fleshed out reconstruction that I have ever seen. This is exactly like it. Eventually over 33, ceramic figurines were found near El Toro as well as Chivo Mountain on the other side of Acambaro.

In , Arthur Young submitted two of the figurines to Dr. The Masca lab had obtained thermoluminescent dates of up to 2, B. In a letter dated September 13, , addressed to Mr. Young, Dr Rainey said: Now after we have had years of experimentation both here and at the lab at Oxford, we have no doubt about the dependability of the thermoluminescent method.

I should also point out, that we were so concerned about the extraordinarily ancient dates of these figures, that Mark Han in our lab made an average of 18 runs on each one of the four samples. Hence, there is a very substantial bit of research in these particular pieces But when the lab at the University of Pennsylvania found out that dinosaurs were part of the collection, they retracted their thermoluminescent dates.

They asserted that the ceramics gave off regenerated light signals and could be no more than 30 years old. A thermoluminescent technician admitted that no other ceramics existed, in his experience, that produced regenerated light signals, and no other thermoluminescent dating of ceramics had ever been done by utilization of a regenerated light signal. In short, the excuse was a hocus pocus, laboratory trick to avoid the obvious conclusion that dinosaurs and man lived together.

John Tierney took a half dozen samples of Julsrud ceramics of different clay composition to a team of experts at Ohio State University. They consisted of Dr. Ehlers mineralogist in the geology department at Ohio State University. The team reported that they could not believe the artifacts were made in modern times, nor could they believe they were made by some amateur who tried to perpetuate a fraud.

Upon my notifying them that they had authenticated Julsrud artifacts, they lapsed into a profound and apparently permanent silence. Toward the end of the program, it is revealed that he sent two samples of Julsrud-type ceramics a human figure and a dinosaur figure to an independent Carbon laboratory.

Startling results came back. Steede tap danced around the implications, embarrassingly embracing the human figurine as credible, while waltzing past the dinosaur figurine, claiming the laboratory test must not have given a true reading.

In reality, the dinosaur figurine created too much tension for orthodox science and Steede had to find an out. The solution was simple. He discarded the dinosaur date. The Japanese company Nissi sponsored a television crew to go to Acambaro and produce a program for Japanese T. The program entitled "Did the Ancients See Dinosaurs? But this is still a factor to heavily consider between objects dated near the equator versus near the poles.

Human activity has also played a large role in C14 production. Only specimens that lived prior to the advent of nuclear weapons usage can be carbon dated since nuclear blasts created an influx of C14 in our atmosphere Warf, Fossil fuel consumption also wreaks havoc with the atmospheric ratio between C12 and C This is known as the Suess Effect Taylor, Between to C14 levels were steady.

As mentioned earlier, tree ring samples, which can be radiocarbon dated, can give us insight into the past as to what the historical atmospheric ratios of C12 to C14 were. This was needed because the first radiocarbon dating methods were yielding very inconsistent dates regarding objects of known age. In the s an 8, year old tree ring sequence was established by Wesley Ferguson, which when compared to the radiocarbon dates, revealed large discrepancies.

Calibration curves were established in light of these discrepancies and can go back to 2, BC Bowman, As useful as the calibration curves are, they only go back as far as the tree ring chronology. Using live trees and preserved dead trees mostly bristlecone pine trees a master tree-ring chronology has been established going as far back as 8, years Snelling, Tree ring chronology is known as Dendrochronology.

No items can be accurately dated within the time span of BC to BC because the calibration curve during this time falls flat. In fact, many labs will not date objects believed to have been from this time for that very reason Bowman, Other issues with dendrochronology lie with the trees themselves.

Ring patterns in trees are produced season to season, year to year, and fluctuate depending on temperature and precipitation Snelling, In other instances trees have been observed to grow multiple growth rings in one season Snelling, This means that the dendrochronology relies on an additional assumption; that tree rings are a seasonal constant.

Since there is no guarantee they are a seasonal constant, we have no way of knowing exactly how far back the tree ring chronology goes. Chronologies can only be established when comparing the same species of trees in the same location. When there are no overlapping areas between older and younger trees, and thus a gap, a floating chronology is established. If missing links of wood are found radiocarbon is used to piece and the fit the wood into the overall chronology Snelling, This is troubling because it becomes a circular system; tree ring chronology is used to calibrate radiocarbon dating, yet radiocarbon dating is used to date the tree rings.

So the assumption that C14 production is constant is incorrect. Though dendrochronology has allowed for calibration adjustments accounting for the production variations, the chronology goes back less than 10, years and even so, there is no guarantee that the tree rings are as accurate in chronicling the passing of years as many make them out to be. In one way it can be seen as an assumption to rescue another assumption.

What is known is that C14 production has varied in the recent past, so it has surely varied greatly in prehistory as well. Assumption 2 C14 rapidly mixes and is spread evenly throughout the biosphere. For the ability to be realized, C14 must be mixed quickly within a few years and completely throughout all of the carbon-containing reservoirs.

If such a condition prevailed, the contemporary C14 content of all organic samples would be essentially identical. Though we have already covered that C14 production has been a historical variable, now we come to the issue of mixing. Atmospheric mixing between the stratosphere and troposphere takes 2 to 4 years Taylor, However, when C14 production is high, atmospheric mixing is quick. But when production is low, atmospheric mixing slows and C14 is thus not distributed globally quickly.

Furthermore, the biosphere does not absorb C12 and C14 equally Bowman, Organisms have been proven to ingest more C12 than C13, and more C13 than C Regardless of the atmospheric ratio of C12 to C14, organisms will consume a higher ratio of C12 atom per every C14 atom than that of the atmosphere Bowman, Another problem is that of ice ages.

During the ice age s the biosphere contained less plant life. Additionally, colder water temperatures globally would have increased the solubility of carbon. Thus, during cold periods like the ice age, which extends into the time ranges of C14 dating, the C14 exchange globally was not the same as today.

The last ice age is believed to have peaked 20, years ago. This cuts right into the age span that radiocarbon dates for. The marine effect is an example of a reservoir effect in that the ocean has less C14 concentrations. Though atmospheric and terrestrial biosphere environments can mix C14 quickly, the ocean cannot mix quickly, especially the deeper you go. Ocean mixing is so slow that there are deep areas where radiocarbon dating would reveal radiocarbon ages in excess of a few thousand years.

Shallow waters take about 10 years to equalize, but deeper waters are not quantifiable because of unique currents and upwelling effects Bowman, Evidence of the marine effect is obvious when one tries to date sea life. In one example, shells dated in two different locations but in close proximity dated centuries apart Bowman, Marine animals like whales and seals show radiocarbon ages of hundreds of years Bowman, Bottom feeding fish often exhibit old age because of reservoir effects Taylor, Even shallow marine life can be affected by the reservoir effect.

The Colorado River before it was drained would carry large amounts of carbon, from the limestone rock it flowed over, into the Sea of Cortez. The only way to accurately date sea life is if the reservoir effects and the value of stable carbon isotopes are known Taylor, Scientists have proposed average correction factors reservoir age estimates to introduce to dating marine life, but these factors are far from absolute due to the nature of slow upwelling mixing which can vary from wind, climate, coastline shape, near-shore currents and seafloor topography Taylor, While atmospheric mixing is good within hemispheres, it is not good between them since winds rarely blow between the two.

When volcanoes erupt they release large quantities of CO2 that contain no C This dilutes the ratio of C12 to C14 in the atmosphere Bowman, Plants near volcanoes typically exhibit high ages because of this. Vegetation found on the volcanic island of Santorini often carbon date in excess of thousands of years Bowman, Carbon dating volcanic debris is wrought with controversy because of this.

Assumption 3 Carbon ratios are only altered by C14 decay after an organism dies. In order for radiocarbon dating to accurately gauge the amount of time that has passed since the organism died, the radio decay of C14 must be the only factor influencing the ratio of C12 to C14 within the organism.

Any other factor influencing the ratio other than C14 decay is contamination. This problem of contamination is quite a thorn in the side of radio carbon dating because it is very common.

Hard water often has calcium ions in it from calcium carbonate. This adds additional carbon into the plant or animal that takes it in. Since hard water varies from region to region, especially over large time scales, it is an unquantifiable variable.

Other similar unquantifiable variables that contain carbon are soil humus materials and carbon dioxide in soil. Unfortunately, many incredibly valuable finds, like bones, are easily susceptible to hard water contamination. Bones are prone to absorb waters in the ground due to their porous nature Taylor, If the water is rich in carbonates, as ground water often is, the bone becomes contaminated with carbon ratios that make the bones appear much older than they actually are.

This is usually done with acids. But not all contaminants can be removed, neither can they, at times, be identified for that matter Bowman, For example, a human body was found in a peat-bog in Cheshire England.

The carbon rich bog was united with the carbon rich body. This mixing of carbon proved to be problematic. Two forms of carbon dating were used; conventional gas counting and AMS. The conventional dating placed the man to the fourth and fifth centuries Bowman Another source of contamination comes from microorganisms.

Microorganisms can contaminate samples causing 1, to 2, year discrepancies. The longer a sample is exposed to microorganisms the greater the chance of contamination, and subsequently, greater the age discrepancy Taylor, The farther one goes back in time, the more severe contamination becomes. Even objects less than 30, years old can be greatly affected by modern carbon contamination.

Though contamination can be pretreated, and the AMS is so precise it can avoid many contaminants, many other contaminants can slip by unknown if not detected. Some contaminants are so embedded in the sample that they cannot be removed without destroying the sample. The assumption cannot be validated with full certainty. Assumption 4 The half-life of C14 is accurately known. The decay of carbon is not a prediction, but statistical probability estimation.

There is no way of knowing exactly when a C14 nucleus will decay and release a beta particle. Instead, large numbers of C14 atoms are measured over periodic intervals, and overtime there is a normal distribution Taylor, However, because the decay rate of C14 is a statistical estimate, this makes laboratory error estimation difficult as you will read about in the next assumption.

As far as this assumption, we can conclude the half-life is known, and thus the assumption validated, but the nature of the estimation limits error estimation which comes into play in the next assumption.

The first thing to address here is the misconception that radiocarbon dating provides exact points in time for objects of antiquity. Accuracy is the ability to date an object accurate to archaeological dates. Precision is the range of dates determined Taylor, For example, an object might be dated to 1, B. Or that object might miss the mark completely and be dated at 2, B.

Due to the amount of variables involved in carbon dating, results can have varying accuracy and precision. Since radiocarbon dating is a scientific process it is subject to experimental error. And as mentioned in the previous assumption, that the decay of C14 is a statistical probability estimation, it becomes very problematic to derive any concrete error estimations.

In radiocarbon dating, time, cost, and for conventional radiocarbon sample size mean this is not a practical proposition. Another issue in the process of radiocarbon dating is the range of date estimates. Since not every test will give the same result, not every object will give the same result, and the error factor is a mere estimation, the only way to truly generate accurate results is to date multiple samples multiple times to provide a range of results.

Unfortunately, it is often difficult to evaluate directly the various factors that could influence the accuracy of a single C14 value. The conventional radiocarbon methods have been historically fraught with inconsistencies and can be contaminated by other sources of radiation.

Conventional carbon dating also depends on a background count rate, which varies from laboratory to laboratory Bowman, But these issues are not just limited to the older conventional methods, AMS has issues as well. Such materials are Precambrian since nothing that old should have detectable C Yet, these materials have continually been known to give off detectable C14 readings Snelling, So knowing that radiocarbon dating requires multiple tests on multiple samples in order to ensure accuracy and precision, something not commonly done, in combination with the fact that experimental error is not known, but only estimated, it is reasonable to say that this assumption cannot be validated beyond reasonable doubt.

It thus remains an assumption open to inquiry. Assumption 6 C14 decay rates and formation rates are in equilibrium. This assumption, unlike the others, is very straight forward. C14 formation and decay must be in constant equilibrium for radiocarbon dating.

Currently, the rate at which C14 decays is not in equilibrium with the formation rate. This ratio may swing in either direction depending on variables in C14 production. Either way, this assumption is false. Outside of the assumptions, there are other issues that come into play within the radiocarbon dating process. As a tree grows and adds rings the outer rings continue to exchange carbon whereas the older internal rings do not.

Thus, if one were to date the heartwood vs. This is even greater if the tree aged to hundreds of thousands of years Bowman, This poses a problem for modern artifacts because the only way to accurately date the wood is to know how old the tree was and whether the wood was from the inner heartwood or outer sap wood Bowman, The only way to date wood with radiocarbon is if the sapwood and heartwood are identifiable.

After which, the rings can be dated backwards from the sapwood to the heartwood to calculate the age of the tree. This is also known as the Delayed Use problem.

Are tree-ring chronologies reliable? - C14 dating method

Though we have already covered that C14 production has been a historical variable, now we come to the issue of mixing. The "bone bed is characterized by the presence of completely disarticulated skeletal elements at various stages of c14 development". A critical assumption used in carbon dating has to do with this ratio. When they die, they stop exchanging carbon dating the biosphere and their carbon 14 content then starts to decrease at a method determined by the law of radioactive decay.
