Carbon-14 dating decontaminated dinosaur bones

The preferred method of dating dinosaur fossils is with the radiometric dating method. And the result of this accepted method dates dinosaur fossils to around 68 million years old. However: Consider the C decay rate. The theoretical limit for C dating is , years using AMS, but for practical purposes it is 45, to 55, years.

The radioactive carbon combines with oxygen to form carbon dioxide and is incorporated into the cycle of living things.

Why Carbon Dating Might Be in Danger

This changes the atomic number of the nucleus to 7, producing a nucleus of nitrogen At equilibrium with the atmosphere, a gram of carbon shows an activity of about 15 decays per minute. The low activity of the carbon limits age determinations to the order of 50, years by counting techniques.

The bone was 68 million years old, and conventional wisdom about fossilization is that all soft tissue, from blood to brains, decomposes. How do scientists know the bones are really 68 million years old? Today's knowledge of fossil ages comes primarily from radiometric dating, also. All about Fossils and Carbon Dating: Dinosaur Teeth and More for Kids. Fossils are the The first element used to determine the age of fossils was carbon But carbon dating won't work on dinosaur bones. Some of the isotopes used for this purpose are uranium, uranium and potassium, each of.

Some creationists seem to understand that rocks and minerals cannot be dated using the Carbon 14 technique. This is a quote from the CMI website and it is accurate:.

Creationists bring up Carbon 14 dating of dinosaur bones all the time. This shows a lack of basic understanding of how the method is used and what material it. Why is there Carbon 14 in Dinosaur bones? Is it possible that it is background Carbon 14, or is it a contaminate?. That would be very unreliable indeed. Radiocarbon dating cannot be used to date anything that hasn't been alive in the last years or so.

We know how quickly C14 decays, and so it becomes possible to measure how long it has been since the plant or animal died. It seems what creationists fail to understand is dinosaur bones are permineralized or at the very least, partially permineralized, and therefore they no longer qualify as "once living material.

Considering Contamination

Even soft tissue has shown to be preserved with minerals such as iron rendering the method useless for dating. Incidentally, while I was looking for your first link I found this one from back in I thought it did a good job presenting what Schweitzer saw her research as and how it was co-opted by other groups.

Regarding soft tissues, I came upon this blog that is a great overview. Lots other I interesting articles also:. He must have taken Every One of those Animals alive on the Earth because they do not share the fossil record with all of the Flood victims!

At a horizon of 40, years the amount of carbon 14 in a bone or a piece of which extent it can be used to obtain a good estimate of the age of the bones. What they got was a date for the shellac, not the dinosaur fossils. Did you know that Carbon has been found in dinosaur fossils? But other dating methods used to show ages of millions and billions of years are open to the. Dinosaurs went extinct 65 million years ago. To determine the age of a dinosaur fossil, carbon dating can never be used. Carbon only works for fossils less.

The work by Mary Schweitzer and her colleagues has shown that at least some of the flexible tissues from deep within the dinosaur bones she examined is original organic material, not merely recent biofilm. However, these tissues have been significantly stabilized by cross-linking in the course of aging.

While there is evidence for some heme units heme is a stable portion of hemoglobinthere are no actual red blood cells. For other fossil dinosaur samples, it is possible that the flexible material found in them is recent bacterial biofilm, not original organic molecules.

Is carbon dating used for dinosaurs

Thomas Kaye presented convincing evidence that some of the flexible material he extracted from fossil dinosaur or turtle remains was biofilm.

He also found that little red objects which initially looked like red blood cells in blood vessels were actually microclusters of iron oxide.

That scientists are unable at present to give a complete account of the mechanism and trajectory of the preservation of modified proteins in the dinosaur bone pores is not some unique, embarrassing case. This situation arises constantly in the course of scientific discovery. But when genuine science is brought to bear on these issues, they are eventually readily explained within the framework of an old earth and accepted physics.

It may take some years, however, to come to a satisfactory resolution. A number of these supposed evidences for a young earth are exposed here.

How Do Scientists Determine the Age of Dinosaur Bones?

The absence of long, sequenceable chains of DNA in any dinosaur fossils indicates that these fossils are much older than the year age allowable in young earth creationism. The same held true for sequences of proteins.

  1. In my opinion you are not right. I am assured. I suggest it to discuss. Write to me in PM, we will communicate.
