How Do Scientists Determine the Age of Dinosaur Bones?

How Do Scientists Determine the Age of Dinosaur Bones?

The finding radically suggests that early humans may have once walked the earth with the fearsome reptiles thousands of years ago. Classical reconstruction of a Triceratops Wikimedia Commons Until recently, Carbon dating was never used to test dinosaur bones, as the analysis is only reliable up to 55, years. This is then incorporated into plants by photosynthesis, and animals acquire 14C by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and from that point the amount of 14C it contains begins to reduce as the 14C undergoes radioactive decay. Measuring the amount of 14C in a sample from a dead plant or animal such as piece of old wood or a fragment of bone provides information that can be used to calculate when the animal or plant died. The oldest dates that can be reliably measured by radiocarbon dating are around 50, years ago, though special preparation methods occasionally permit dating of older samples. I hope this is a joke because its stupid. I think he is a creationist, Hugh Miller.

He had investigated the extraordinary claims that had been first presented in Alternative 3, an episode of a British television documentary series called Science Report, which aired on June 20, Alternative 3 The Alternative 3 television show described how the deterioration of global environmental conditions had led to the major powers, US and USSR, secretly collaborating behind the scenes to ensure survival of the human species.

This included Watkins whose investigation uncovered more information that led him to writing the book, Alternative 3. For obvious reasons, we cannot reveal the identity of Trojan. Nor can we give any hint about his function or status in the operation. We are completely satisfied, however, that his credentials are authentic and that, in breaking his oath of silence, he is prompted by the most honourable of motives.

Carbon 14 is used for this example: This nullifies the carbon method as well as demonstrating that the earth is less than 10, years old. The above is offered as a simple fact of research. Knowing how faulty creationist “facts” can be, let’s do a little research of our own. One suspects that the scientific world would not be using the carbon method if it were so obviously flawed.

Could it be that the whole scientific community has missed this point, or is it another case of creationist daydreaming? This argument was popularized by Henry Morris , p. In another creationist, Robert L. Whitelaw, using a greater ratio of carbon production to decay, concluded that only years passed since carbon started forming in the atmosphere! The argument may be compared to filling a barrel which has numerous small holes in its sides.

Considering Contamination

From to Allied and Axis scientists threw their weight into the war knowing that their influence would have enormous consequences for mankind. The secret battles for air supremacy, the inventions, the measures and the countermeasures are part of a story which scientists tell in tonight’s programme. A Scottish chemist has recently thought up an unusual application for Scotch whisky:

Of course carbon dating of dinosaur bones gives a C14/13 ratio that indicates an age of less than , years. Carbon only has a half-life of about 5, years and after , years there’s virtually no carbon left to measure and nowhere near enough to make a reliable age measurement.

C14 Dating of Dinosaur Bones

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 main point of the debate seems to be the following: Over the past decades, several research groups of self-proclaimed creationist scientists have claimed discoveries of dinosaur bones that they have managed to date, using radiocarbon dating methods , at some age which is a lot below the ‘usual’ i. The age that these groups claim to find is usually on the order of thousands or tens of thousands of years old.

The particular example you bring up is one of the most famous such cases. The claims are really quite spectacular, when taken at face value, and therefore should be examined thoroughly. In this answer, I will try to go through this story in great detail, hopefully exposing the reasons why this work is not taken seriously by scientists. The research by Miller et al. A research team from the CRSEF, or Creation Research, Science Education Foundation, led by Hugh Miller, has claimed to have dated dinosaur bones using radiocarbon methods, determining them to be no older than several dozens of thousands of years old.

Let’s look at their research methodology in detail indicated by bullet points: As it turns out, Miller’s research group obtained their sample in quite a remarkable way. In fact, the creationist posed as chemists in order to secure a number of fragments of fossilized dinosaur bone from a museum of natural history, misrepresenting their own research in the process of doing so. When the museum provided the bone fragments, they emphasized that they had been heavily contaminated with “shellac” and other chemical preservatives.

Miller and his group accepted the samples and reassured the museum that such containments would not be problematic for the analysis at hand.

This is what archaeologists use to determine the age of human-made artifacts. But carbon dating won’t work on dinosaur bones. The half-life of carbon is only 5, years, so carbon dating is only effective on samples that are less than 50, years old. Dinosaur bones, on the other hand, are millions of years old — some fossils are billions of years old.

This business of taking the age of the earth and proving it is billions of years old by looking at carbon dating, uranium lead, potassium argon, and rubidium, is all backwards. the magnetic field is one of the things that prevents the formation of carbon 14 (C) If the magnetic field is weakening, then we are getting more C14 than they.

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. 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.

How Good Are Those Young-Earth Arguments?

Triceratops Horn Dated to 33, Years Read the article on one page A Triceratops brow horn discovered in Dawson County, Montana, has been controversially dated to around 33, years, challenging the view that dinosaurs died out around 65 million years ago. The finding radically suggests that early humans may have once walked the earth with the fearsome reptiles thousands of years ago. The Museum, which has since been in cooperation with the Paleochronology Group, a team of consultants in geology, paleontology, chemistry, engineering, and education, sent a sample of the outer portion of the Triceratops brow horn to Head of the Paleochronology Group Hugh Miller, at his request, in order to carry out Carbon dating.

Mr Miller told Ancient Origins that it is always desirable to carbon date several fractions to minimize the possibility of errors which Miller requested and that essential concordance was achieved in the ‘s of years as with all bone fractions of ten other dinosaurs. Classical reconstruction of a Triceratops Wikimedia Commons Until recently, Carbon dating was never used to test dinosaur bones, as the analysis is only reliable up to 55, years.

A Review of Walt Brown’s book and hydroplate theory. Earth Boiled, Steamed and Roasted Another serious problem with Brown’s model is the immense heat that would be generated during the proposed cataclysmic eruptions (Castagnoli, ; Morton, ), which would have literally boiled the oceans and steamed to death all animals and humans aboard Noah’s ark.

The Oldest Living Thing: The oldest living thing on earth is either an Irish Oak or a Bristlecone pine. If we assume a growth rate of one tree ring per year, then the oldest trees are between 4, and 4, years old. Also, with regard to fossil tree rings, the author has been unable to find any documented instances of fossil trees having more than about rings. This is significant since we are told that God literally made the Earth, and all that is in it, only about years before the Noachian Flood described in the Book of Genesis.

In a Bristlecone Pine tree was discovered that has just over 5, tree rings. Helium in the Atmosphere: Helium is a byproduct of the radioactive decay of uranium as it decays into various different elements into its final stable element: As it decays, the helium not only accumulates in the rocks themselves, but also escapes from them and accumulates in the earth’s atmosphere. They also know how much helium is currently in the atmosphere. If we use the same assumptions that radiometric dating experts make: Thus, after several hundred revolutions they disintegrate.

Although some people claim that the Kuiper belt has been discovered, to this author’s knowledge that is not the case. Nor has even one hypothetical object i.

Why have there been no human fossils found amongst dinosaur fossils?

They will not allow others to date bones in their possession! Our Paleo team has Carbon 14 dated dinosaur bones from Texas, Colorado, Montana, China, North Dakota, and Alaska by professional labs using accelerator mass spectrometry. Every sample dates to between 23, and 39, years before the present. Did Asteroids kill the dinosaurs?

When did Asteroids hit. See below and on our Carbon 14 dating page.

That over half of our ministers really believe that the universe is only around 10, years old.

A brilliant way to muzzle Christians: Craig vs creation days Craig recently gave a series of talks where he attacked the biblical creationist view on the days of Genesis 1. Any honest attack on a particular view should address the strongest claims for this view, which in turn demands that the critic should address the leading works defending this view.

However, it becomes abundantly clear that Craig lacks the slightest familiarity with the leading creationist works on the issue see recommended material, top right, for those from CMI. This will be demonstrated in the responses to his main points below:

Dinosaurs became extinct about 65 million years ago, long before any humans existed. The reason why scientists who study dinosaurs reached this conclusion is radiometric dating of the rocks in which dinosaurs fossils are found.

A sample that is more than fifty thousand years old shouldn’t have any measurable C Evolutionists admit they are finding so many instances of C in million-year-old samples, they gave up trying to find large quantities free of C You’re just cutting and pasting NCSE talking points, not actual reported lab and field observations. And furthermore there are some supposedly tens-of-millions-of-years-old fossils with 22, year dates which mean they have greater than 6.

It’s not a Geiger counter or some other similar instrument counting radioactive emissions. It doesn’t count emissions, it counts isotopic ratios. Please tell me you know that beta emissions counts are not the same thing as isotopic ratios. An AMS machine can distinguish something like the isotopes of Tin mean atomic mass Radiometric C14 dating isn’t the same as counting radioactive decays in real time. The above is a total distortion of what is being measured.

Radiometric C14 dating is about determining and comparing carbon isotopic ratios not real time beta decay rates. Perhaps you should follow your own advice instead of posting confused science that insinuates C14 dating is something akin to using Geiger Counters instead of Accelerator Mass Spectrometers. If you don’t know the difference in what the devices actually measure, you should refrain from telling others:

The Philippines are a perfect example of how the Mongol types spread out from Taiwan. Popular belief holds that the majority of Philippine people are descendants of migrants from Indonesia and Malaysia who came to the islands in successive waves over many centuries and largely displaced the aboriginal inhabitants. But modern archeological, linguistic, and genetic evidence, however, strongly suggests that those migrants originated in Taiwan and went on from the Philippines to settle Indonesia and Malaysia.

Pre-Spanish Period The first people in the Philippines, the Negritos, are believed to have come to the islands 30, years ago from Borneo and Sumatra, making their way across then-existing land bridges. According to popular belief, Malays subsequently came from the south in successive waves, the earliest by land bridges and later in boats by sea.

In contrast, modern archeological, linguistic, and genetic evidence strongly suggests that those successive waves of migrants came from Taiwan as the Austronesian sub-group, Malayo-Polynesians.

Kuban last revised Jan. I use this format to avoid webbot spamming Fig. Brown’s website and book showing what he calls the “Rupture Phase of the Flood” Introduction Walter Brown, a young-earth creationist and retired mechanical engineer, has developed a “Flood model”1 which he believes accounts for virtually all geologic evidence on earth, as well as a variety of astronomical phenomena.

His central thesis is that only a few thousand years ago the Earth’s entire crust consisted of a granite slab 20 to 60 miles thick until recently, claimed to be 10 mi thick , suspended over a large reservoir of highly pressurized water. According to Brown, due to centuries of “tidal pumping” from the Moon’s gravity, the crust suddenly cracked and burst open, violently releasing the subterranean water and flooding the entire earth Fig.

He argues that large masses of rock and water were ejected into outer space during this massive eruption, creating all the asteroids, comets, and meteoroids in our solar system. He further claims that the immense slabs of broken crust, which he calls “hydroplates,” undulated, heaved and slid thousands of miles in a matter of months or less, and then crashed into each other to form mountains within hours. Brown presented early versions of the model during the ‘s Brown, , and subsequently revised and expanded it into a more comprehensive model of earth history, which he described in a book entitled In the Beginning: Compelling Evidence for Creation and the Flood, now in its 8th edition Brown,
