Carbon-14 dating decontaminated dinosaur bones
Fossils are the remains of animals or plants that lived a long time ago. When we think of fossils, the first things that come to mind are the bones of dinosaurs; but a fossil can be anything. Footprints, flowers, even droppings; all of these things can be turned into fossils under the right conditions. A fossil only becomes a fossil. Carbon, Radiometric Dating and Index Fossils. Carbon dating is used to determine the age of biological artifacts up to 50, years old. This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be. Some of the isotopes used for this purpose are uranium, uranium and potassium, each of which has a half-life of more than a million years. Unfortunately, these You can learn more about fossils, dinosaurs, radiometric dating and related topics by reading through the links on the next page. Other Dating.
Several tests were done by the University of Georgia using accelerator mass spectrometry. The age for all these fossils was found to be less than 50, years 1.
This is not predicted by conventional evolutionary theory; and other discoveries have been made concerning dinosaurs which also are not predicted by evolutionary theory such as the discovery of soft tissue in bones that are not or are only partially fossilized. Hugh Miller and others authored a paper detailing the results of carbon dating of dinosaur fossils which was presented at the Western Geophysics Meeting in Singapore, August However, the abstract of the Miller presentation was removed from the website for the conference.
If the accepted ages of millions of years for dinosaurs were to be found to be in error, this would be a problem to evolution. The dinosaur dates reported below and discussed in the AOGS paper discussed throughout this article, included triceratops, hadrosaur, allosaurus, and acrocanthasaurs.
Below is a list of some dinosaur fossils and their dated ages from the Miller paper. Are the dates beyond the range of testing technology? No, the University of Georgia had extended the maximum Is Carbon Dating Used For Dinosaurs up over 50, years, and the ages were all well below this. Are the ages still too old?
Dating dinosaurs and other fossils
After all, even though these ages are much younger than conventional ages, many creationists believe life on earth to be much younger than even the reported carbon ages of these dinosaur fossils. This question will be dealt with in a later section of this article. Another question that might come up with respect to these studies is the issue of contamination.
This is mainly due to the nature of bone, which is a very porous material. Scrapings were taken from a large bone excavated go here Joe Taylor of Mt. That is, if they really are over 65 million years old, as the conventional wisdom says. But even if it is true that older radiometric dates are found lower down in the geologic column which is open to questionthis can potentially be explained by processes occurring in magma chambers which cause the lava erupting earlier to appear older than the lava erupting later. It is simply not credible to claim that anything beyond the most rudimentary kind of replication or metabolism could have arisen in free solution.
If young organic material became mixed with the dinosaur material that was carbon dated, then the younger material would skew the result to a younger age. Another report shows that a mosasaur was dated at about 24, years old 78 Is Carbon Dating Used For Dinosaurs this result was blamed on bacterial contamination, though no bacteria were discovered. Living animals take in carbon on a regular basis. After death, the animal no longer takes in any carbon nor any other kind of carbon.
The carbon decays at a known rate, but since it is being replenished while the animal is alive, only after the animal dies is link carbon added. Given the initial amount of carbon, the decay rate, and the remaining amount of carbon in a fossil, the length of time it would take for the initial amount of carbon to decay to the amount measured as remaining in the fossil may be calculated.
Carbon decays with a half-life of about 5, years.
When the museum provided the bone fragments, they emphasized that they had been heavily contaminated with http://24dating.me/j/who-dating-who-in-the-wwe.php and other chemical preservatives. The process of using index fossils is describes by the late Creationist author and Ph. Carbon 14 is used to date things that were once living and in equilibrium with the atmosphere. Then the bone was crushed and acetic acid was applied to remove any possible external contamination carbonates.
So if an object contained 1, carbon atoms, after 5, years Is Carbon Dating Used For Dinosaurs should contain approximately half that many, or carbon atoms. There is one other pertinent point to be made about carbon dating, however. In fact, if the entire earth were solid carbon, in a million years so much would have decayed that there would not be even a single atom of carbon left. Scientists have done studies which suggest that dinosaurs lived millions of years ago, but those dates were not arrived Is Carbon Dating Used For Dinosaurs by use of carbon dating methods.
So, you might ask, why is this article about carbon dating of dinosaurs? That is the point. That statement would be Safely Use How To Sites Online Dating if the dinosaurs were really millions of years old. But, if they were not that old, merely thousands of years old, then carbon dating applied to dinosaur fossils might detect some carbon atoms.
Are dinosaurs only thousands of years old? These findings about dinosaur fossils are just a piece of the evidence indicating assumed ages are perhaps mistaken. Other pieces include carbon in diamonds, other soft tissue found in dinosaur fossils, and evidence that conventional dating methods are inaccurate. Diamonds supposedly formed even further back in the past than dinosaurs —over a billion years ago.
There is even less reason to expect to find carbon in them, but it has been found. Soft tissue normally will deteriorate over time. This is so contrary to conventional theory that the discovery met with disbelief at first. Lava that obviously flowed around a piece of wood, since the hardened lava has taken the shape of the wood, has been dated as having solidified millions of years before the wood existed. The point here is that the evidence of carbon dating presented above is not the only evidence indicating that currently accepted dates for dinosaur and other fossils might be wrong.
Experiments are replicated in the belief that increasing the number of results supporting a hypothesis increases the evidence for the hypothesis. In a similar manner, the more evidence of young ages for dinosaur fossils, the more compelling the evidence in total becomes. Could the dinosaur ages now be said to be precisely what the carbon dating results indicated?

Even this is too old for many creationists, who would expect them to be less than 6 to 10 thousand years old. Several factors may possibly account for this seeming discrepancy. According to this theory, the proportion of carbon Is Carbon Dating Used For Dinosaurs have been higher due to the removal of much normal carbon. The increased humidity before the flood would have reduced the formation of carbon in the atmosphere, while the drier air after the flood would have allowed more carbon formation.
This could make younger fossils yield dates greater than their actual age. Evidence of differing dates for parts of the same animal support the hypothesis that there was a change in the carbon concentration or in the decay rate. One interesting observation is that rapidly-growing body parts, such as hair, would absorb carbon from most recent concentrations, while slower-growing body parts, such as bone or muscle, might contain concentrations of carbon based on levels of carbon existing at earlier times in the environment of the animal.
Triangle Association for the Science of Creation
Therefore, evidence of differing carbon concentrations i. We now will look to see if there is just such evidence. A frozen musk ox found at Fairbanks Creek, Alaska, had scalp muscle tissue 24, years old and hair 17, years old according to carbon dating. At least three other frozen animals, two mammoths and a mastodon, have been found with parts of their bodies with carbon ages far different from other parts or from surrounding plant life that perished with or shortly after the animals.
If the conventionally accepted age of dinosaurs is wrong, then what about other conventionally accepted dates? When was Is Carbon Dating Used For Dinosaurs Jurassic, and the Is Carbon Dating Used For Dinosaurs Other dates are thrown into question. This implies there may be less certainty about the time frame during which species supposedly evolved.
One point that is worth noticing is that these dinosaur ages are all much younger than the conventional ones. This implies there was less time for evolution to occur.
Even with the accepted millions and millions of years for evolution to supposedly have brought continue reading into existence from their precursors, evolution still has many problems.
Shortening the time available just makes evolution even more unlikely. Evolutionists have said the following. Co-occurrence of men and dinosaurs. Such an association would dispel an Earth with vast antiquity. The entire history of creation, including the day of rest, could be accommodated in the seven biblical days of the Genesis myth. Evolution would be vanquished.
There is an infinite variety of ways in which, sincethe general concept of evolution might have been demolished. The unequivocal discovery of a fossil population of horses in Precambrian rocks would disprove evolution.
More generally, any topsy-turvy sequence of fossils would force us to rethink our theory, yet not a single one has come to light. As Darwin recognized, a single geographic inconsistency would have nearly the same power of destruction. The evidence strongly hints that evolution is at best, not on as firm a foundation as many have claimed.
Do we look at the evidence and let it speak, or do we deny the evidence because of our biases? This is the choice we face when please click for source with evidence such as presented in this article.
Theories built on evidence is science; evidence built on theories evidence accepted because of confirmation of existing theories or evidence rejected because it contradicts existing theories is dogma built on bias. Skip to main content.

An apatosaurus was found in late Jurassic strata of the Morrison formation, and excavation was done in and In a triceratops horn was found. A femur bone from a hardosaur in was found in the Hell Creek formation. An acrocanthosaurus carnivorous dinosaur specimen was excavated in near Glen Rose, Texas and was tested in by the University of Georgia. Special care was taken to prevent this kind of contamination. Bones were cleaned by ultrasonics.
Then the bone was crushed and acetic acid was applied to remove any possible external contamination carbonates. Hydrochloric acid was added to dissolve the bone and release carbon dioxide, which was then chemically treated to produce graphite.
This graphite was then tested for carbon Other evidence indicating younger ages for fossils These findings about dinosaur fossils are just a piece of the evidence indicating assumed ages are perhaps mistaken. Carbon in diamonds Diamonds supposedly formed even further back see more the past than dinosaurs —over a billion years ago.
