How Do Scientists Determine the Age of Dinosaur Bones

The Dating Game Question from Bryan: Why is radiometric dating considered accurate? I will give two examples, one speculative and one based on actual observations: I understand half-life, log base-2 calculations and radiometric decay. For example, what if the meteorite that hit the earth and killed the dinosaurs or any other large meteorite was a big ball of lead? We have not found traces of it, therefore, we can only speculate what it could have contained. If it were a big ball of lead and mixed with the elements on earth, it would give the appearance that more U half lives had occurred and give falsely high age outputs. This is just one possibility of something that could throw off parent-daughter nuclide ratio.

Did Humans Encounter Dinosaurs

So how many millions of years old are those fossils? Scientific dating that shows that some dinosaurs are young? What kinds of dinosaurs?

C Dating of Dinosaurs How do we know that dinosaurs lived much more recently than many millions of years ago? It’s in carbon dating, testing which shows that a number of species lived only tens of thousands of years ago, yes dinosaur species.

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. To determine the ages of these specimens, scientists need an isotope with a very long half-life.

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 elements don’t exist in dinosaur fossils themselves.

Dinosaur Soft Tissue is Original Biological Material

Can science prove the age of the earth? No scientific method can prove the age of the earth and the universe, and that includes the ones we have listed here. Further, it has to be assumed that the clock was never disturbed. There is no independent natural clock against which those assumptions can be tested. For example, the amount of cratering on the moon, based on currently observed cratering rates, would suggest that the moon is quite old.

The fossils dated by C were excavated in Alaska, Colorado, Montana, and Texas. Details of the Carbon Dating Between and , the Paleochronology group sent eleven dinosaur bone samples to be carbon-dated by a respected laboratory: the Center for .

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. Lafferty, Dispatch Science Reporter A Columbus creation science group says Soviet tests confirm dinosaurs and humans were contemporaries as recently as 10, years ago, some 66 million years after dinosaurs were supposedly eliminated in a mass extinction.

Soviet scientists Dmitri Kouznetsov and Andrey Ivanov said the tests showed samples of dinosaur bones were 9, to 30, years old.

Dinosaur bones Carbon dated to less than 40, years

An article in the January National Geographic boldly proclaimed: The evidence, however, reveals an entirely different story. Hubbard found elegant drawings of an elephant, an ibex, a dinosaur, and other animals.

The preferred method of dating dinosaur fossils is with the radiometric dating the result of this accepted method dates dinosaur fossils to around 68 million years r consider the c decay half-life t 1 2 is only 5, years that is, every 5, years, half of it decays away.

Biobased Analysis

The assumption that the geologic column is a base from which to calibrate the C dates is not wise. With a half-life of only years, carbon dating has nothing to do with dating the geological ages! Whether by sloppiness or gross ignorance, Dr. Hovind is confusing the carbon “clock” with other radiometric “clocks.

However, if a bone an evolutionist thinks is a million years old contains any detectable carbon, the bone is probably less than , radiocarbon years. Bones or other organic remains that contain enough carbon and are believed by evolutionists to be older than , years will be shown to be relatively young in blind radiocarbon tests.

However, the power and rituals of the Knights soon began to unnerve both the Pope and the King of France, who tried to overthrow the Order through persecution and arrests. Webster tells us more: The King of France, Philippe le Bel, who had hitherto been the friend of the Templars, now became alarmed and urged the Pope to take action against them; but before the Pope was able to find out more about the matter, the King took the law into his own hands and had all the Templars in France arrested on October 13, The following charges were then brought against them by the Inquisitor for France before whom they were examined: The ceremony of initiation into their Order was accompanied by insults to the Cross, the denial of Christ, and gross obscenities.

The adoration of an idol which was said to be the image of the true God. The omission of the words of consecration at Mass. The right that the lay chiefs arrogated to themselves of giving absolution.

Jim johnson investigates viking bones. Until recently, years old. And environmental sciences such as radiocarbon dating the age of biological artifacts. Willard libby, years ago? How old. Love-Hungry teenagers and dinosaur bones. This article, years ago. C .

J A Oh, and darn dragons is really insightful right. Kim Sorry I offended u. Personally, we are saddened by your lack of education. Kim I am from the south. Actually northern Oregon, however u wanna look at it. I barely finished law school. I guess we all have our opinions. I need to be more respectful of some, even if I believe they are wrong or stupid. John How do you know your god exists? Hammerstrike Simple, There are likely dinosaurs still alive today, known by the locals. The creature, Mokele-Mbembe, kill hippopotamuses, its likely competitors.

Where it is said by the natives to exist, there are indeed no hippopotamus to be found. Where dragons inspired by just a few bones and skulls?

Assorted retorts from yahoo boards and elsewhere: Collagen and C in Dinosaur Bones

Is it because the results routinely show man and dinosaurs lived at the same time, thus totally destroying the religion of evolutionism, or is there another reason? Why are the bones assumed to be millions of years old? And if they are, why do they have C14 in them according to those that have tested them? Anything even over , years old should have no detectable C14 in them. Scientists routinely use C14 dating on the bones of mammoths, giant sloths, saber tooth tigers, and other similar ancient animals.

Why when they show C14 in them, that indicates they are tens of thousands of years old according to the test; however, if the exact same tests are done on the bones of

> The theoretical limit for C dating is , years using AMS, but for practical purposes it is 45, to 55, years. The half-life of C is years. If dinosaur bones are 65 million years old, there should not be one atom of C left in them.

Welcome to the home of The Question Evolution Project. Presenting information demonstrating that there is no truth in minerals-to-man evolution, and presenting evidence for special creation. Others tried to downplay and ignore them, but they’re here — and they’re spoiling Darwin’s party. It shouldn’t be a surprise to learn that Darwin’s disciples are loathe to have dinosaur fossil tissue tested for carbon After all, that would mean their deep time presuppositions are wrong.

No soft tissues in this bad boy, he’s entirely concrete. Other evolutionists have resisted having specimens carbon tested as well.

Dinosaurs Dated by Carbon Testing

I’m not “ignoring” anything. I’ve pointed out several times now that this fits well with contamination. The fact that it is in a narrow range makes this even more clear. Here we have several samples prepared the same way by the same group in the same lab showing around the same amount of contamination. How is that surprising?

Carbon c dating of multiple samples of bone from 8 dinosaurs found , the discoverer of radiocarbon dating and nobel prize baskets of flowers placed before them, garlands, which they intended for the same mournful yet, gentlemen but you how old are fossils are right we must have to go by.

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. Not only has dinosaur blood blood vessels, and collagen been found and confirmed by the whole scientific community, now fragments of collagen and iron rich proteins have been found within the walls of blood vessels.

Scientists descrribe it as a “startling find” especially since the dinosaur bone it was found in was reported to be million years old. Dinosaur organic matter found Imagine the impossibility of a dinosaur bone not turning to stone, not decaying and crumbling to dust and the contents inside the bone surviving. What is involved would be million years of summer, winter, rain, snow, droughts, floods, earthquakes, crustal movement, perhaps a million or more of these events and yet this bone with its organic matter is still there.

A few years ago scientists worldwide agreed that no organic material could ever survive beyond thousands of years.
